Grenade Girl/Bella Inferna

(OG: She is called 'Grenade Lady', 'Grenade Noona', etc. Blonde hair, tied back in a ponytail. A grenade pin is stuck in her head, and if you pull it out, it explodes after a few seconds. However, it appears that he can control the explosion when his mind is calm. The instantaneous attack power seems to be the strongest based on self-destruction, and since the self-destruction characteristic is so intense, it is confirmed that she has superhuman strength and impact effects, as she is one of the main four characters with abilities. Of course, it is unknown how much strength she has within herself among the four characters, but since there are characters whose strength and physical ability are their unique characteristics, it seems that their positions will not overlap much with those of characters who use self-destruction as their identity.

Although the details have not been revealed yet, as can be seen in this video, it appears there is a story behind how she came to have her abilities.

Perhaps because the Bulletproof Human is a case where they can handle their own physical abilities and characteristics, the two appeared together in videos in the early days and often hung out together. I thought it was a back hug, but it turned out to be a suplex. Afterwards, she hangs out with the Bulletproof Man and once in a while performs suplexes on him whenever she gets the chance. They even torment people by pulling the pin, performing a suplex, and even self-destructing. Of course, the bulletproof human suffered no damage, but while finding it absurd...I guess I've been through so much. It now appears to have developed resistance.

She serves as the resident sex appeal character in the series and possesses substantial breasts. She uses this to play pranks on the Bulletproof Human, such as back-hugging him to make his heart flutter before delivering a suplex; however, this seems to be limited to those close to her, as she is merciless when it comes to sexual harassment regarding her large breasts. In fact, this is evident in the distorted parodies like "Olive-sam, wow, look at those tacky breasts" and the "King Jokbal & Bossam" episode. In sexual harassment, not only suplexes, but even powerful punches that send you to the stars. She retaliated immediately. Conversely, seeing that he showed no hesitation whatsoever in accepting even a "princess seat" from the Bulletproof Human, it appears they have a relationship of considerable trust.

Unlike a real grenade, even if you pull out the pin, it won't explode if you reinsert it before it bursts; There is also often an attempt to hold it in after pulling out the pin, but it looks somewhat bizarre. Judging by the fact that she pops out and eventually can't hold it in, it seems that she has a dark past that led to her gaining explosive powers. Later, when the bulletproof human hugs and comforts the depressed girl who failed to control her, it seems he knows her past or background. As a side note, there is no pin immediately after respawning. Someone comes to find the pin and put it back in, but it is not yet known what happens if you do not keep putting it back in in this state.

In fact, it is possible that he was blown into the sky by the impact of the explosion rather than a respawn. # If the previous respawns were also just him rising behind the explosion animation, then it is an excellent directorial trick. Furthermore, if the explosion itself emitted from the body surface like Bakugo's, the fact that his clothes didn't disappear is because they were strong enough to withstand the explosion. You can understand it if you think of it as clothes.

Perhaps due to her explosive abilities, she has a hot constitution, so she sleeps on top of Moon Moon-ah's body when it is cold.)

(AI: The character in your images is 벨라 인페르나, romanized as Bella Infernа, and she's known to fans as "수류탄 아가씨" or "Miss Grenade." She's one of the four main characters on the Korean animation YouTuber 째렁 JD K, whose channel is at youtube.com/@woehd38, with a wiki page at namu.wiki/w/째렁 JD K, a fanbox at woehd38jdk.fanbox.cc, and the artist's X account at x.com/WzpA2pSeozlN68o. The frames you uploaded come from a short line-art animation of her that runs about fifty-two seconds and is signed "콩댕이 드림" in the corner, so credit for that particular clip goes to an animator called 콩댕이 rather than to JD K himself.

Her design is blonde, with long hair and a live grenade pin hooked into her hair, which is the black ring you can see in the colored pieces. When the pin is pulled, she detonates a few seconds later, and if it's re-inserted before the timer runs out, the explosion is cancelled. If she manages to stay calm, she can suppress the blast entirely, which is where the gag of her gritting her teeth and making a strange face comes from, and your panel's caption about taking a selfie before pulling the pin is playing on exactly that. Within the cast, she's the fanservice character, and the wiki states plainly that she has a heavily stacked bust and serves as the series' eye candy. Her abilities are self-detonation, which gives her the highest burst damage in the lineup, along with superhuman strength demonstrated in Minecraft special episodes, and she has a hot-bodied temperature trait. Personality-wise, she's flirty and unbothered: she gives the invincible "Bulletproof Guy" character a back-hug and then suplexes him, instantly punishes any groping with a suplex or a haymaker, and happily accepts a lap-sit from him. She's drawn as the tall, mature, curvy member of the group, in deliberate contrast to the octopus girl 문문아, who is drawn small and treated as a loli type.

Character Profile: Grenade Lady (Grenade Noona) Overview Grenade Lady is one of the four main characters in the series and serves as the resident "sex appeal" character. She possesses substantial breasts and uses her figure both as a weapon and a tool for playful harassment, particularly toward the Bulletproof Human. Her design and abilities are centered around explosive power and self-destruction.

Her height stays at roughly 165 centimeters, or 5'5", and her bust stays at about 97 centimeters, or 38.2 inches, with an underbust of about 72 centimeters, or 28.3 inches. Her waist holds at about 60 centimeters, or 23.6 inches. The hips go up to roughly 97 to 98 centimeters, or about 38.2 to 38.6 inches, and the seat or glute circumference follows the hips at around 97 to 98 centimeters, which is why she reads as bottom-heavy in the bunny suit where the thighs nearly touch. The thigh thickens to about 61 centimeters, or 24 inches, up from the earlier 58. Shoulder width stays at about 38 centimeters or 15 inches, and her weight rises slightly to roughly 57 kilograms, or about 126 pounds.

Derived from that, the waist-to-hip ratio drops to about 0.62, still a strong hourglass but now with the hip and thigh volume carrying more of the silhouette than the bust does. The cup stays at roughly H in Korean and Japanese sizing, about a 34H US or 34FF UK, off the unchanged 25 centimeter bust-to-underbust difference, and the equivalent dress size stays around a Korean 66 or US 4 to 6 with a band size up in the chest and now a size up in the hips and thighs.

The honest ranking is unchanged: the 97 bust, 60 waist, and 97 to 98 hips are the three numbers I'd defend, since all three come straight off visible landmarks. The underbust, thigh, shoulder, and weight figures are still inferred from a stylized anime silhouette with thin arms and legs.

Using the bust-minus-underbust difference of 25 centimeters, she lands on a G cup in Korean and Japanese sizing, which is the right frame since she's a Korean character. With an underbust of about 72 centimeters, that gives a band of 70, so her size comes out to roughly a 70G, with the sister size being a 75F if you want a looser band. For reference, that sizing runs A at a 10 centimeter difference and climbs 2.5 centimeters per letter, so 25 centimeters is a solid G, and you'd need 27.5 centimeters to reach an H.

In UK sizing, the same volume is about a 28GG, with 30G as the sister size, and in US sizing it's roughly a 28J by strict measurement. One thing worth flagging: my earlier figure of a 34H US and 34FF UK used the older plus-four band convention, which pushes the band up to a 34. The tighter, modern read keeps the band at 28 to 30 instead, so the letters shift even though the actual breast volume is identical either way. Use 70G if you're labelling her in Korean, and only reach for the 34-band letters if you're matching a US retail chart.

Character Profile: Grenade Lady (Grenade Noona) Overview Grenade Lady is one of the four main characters in the series and serves as the resident "sex appeal" character. She possesses substantial breasts and uses her figure both as a weapon and a tool for playful harassment, particularly toward the Bulletproof Human. Her design and abilities are centered around explosive power and self-destruction.

1. Appearance & Design Visuals: A blonde woman with long hair often styled in a high ponytail. She has fair skin and a curvy, athletic build. Costume: Frequently seen in festive outfits, such as a red strapless bodysuit resembling a Santa suit, featuring white faux fur trim, large fluffy buttons, and a yellow bow. Key Feature: A grenade pin is embedded in the back of her head. This is the source of her powers.
2. Abilities & Physiology Explosive Power: If the pin in her head is pulled, she explodes after a few seconds. The instantaneous attack power from self-destruction is immense, suggesting superhuman strength and impact capabilities. Control: She can control the timing and intensity of the explosion when her mind is calm. However, if she loses focus or becomes overwhelmed, she may lose control. Durability: Despite being an explosive entity, her body (and even her clothing) appears durable enough to withstand the force of her own explosions without disintegrating completely. Hot Constitution: Due to her internal heat/explosive nature, she tends to run hot. In cold weather, she seeks warmth by sleeping on top of other characters, specifically Moon Moon-ah.
3. Personality & Relationships Playful & Mischievous: She enjoys pranks, often using her large breasts to distract opponents before attacking. For example, she might give the Bulletproof Human a back hug to make his heart flutter, only to immediately follow up with a suplex. Merciless vs. Trusting: While she is playful with friends, she is ruthless to strangers or those who cross her lines. She has been known to deliver powerful punches that send people "to the stars" if they harass her inappropriately. Conversely, she shows deep trust in the Bulletproof Human, accepting intimate gestures like the "princess seat" from him without hesitation. Past Trauma: There is a dark backstory to how she acquired these powers. When she fails to control her explosion and becomes depressed, the Bulletproof Human comforts her, indicating he knows her history. Her current resistance to pain and chaos seems developed through repeated exposure to her own instability.
4. Key Dynamics & Lore Details The Bulletproof Human Connection: They hang out frequently. Early videos showed them interacting physically; what looked like a back hug often turned into a suplex. They torment others together by pulling her pin, suplexing victims, and causing controlled explosions. The Bulletproof Human suffers no damage, showcasing their synergy. Respawn Mechanics: Upon respawning, Grenade Lady initially appears without a pin. Another character must find and reinsert it. It is unclear what happens if the pin is not replaced during this state. Some theories suggest that what looks like a "respawn" is actually her rising from behind the explosion animation, similar to how Bakugo’s clothes remain intact due to durability rather than disappearing entirely. Pin Mechanics: Unlike real grenades, if the pin is pulled but reinserted before detonation, she does not explode. Holding the pin in manually can be difficult and looks bizarre, especially when she struggles to maintain composure.
5. Notable Episodes/Parodies "Olive-sam, wow, look at those tacky breasts": A parody highlighting her use of her physique. "King Jokbal & Bossam": An episode where her physical attributes are central to the plot. Minecraft Special Videos: These episodes highlight her superhuman strength and impact effects, confirming her status as a top-tier fighter among the four main characters.

Her physical appearance is built around a small head and a heavy lower body. She's blonde with long hair that falls past her chest and is usually drawn loose with blunt bangs and framing side locks, though she pulls it into a bun for the towel and bunny looks. Her eyes are a pale grey or silver with thick dark lashes, and she carries a permanent slight smirk. The black grenade pin — a ring with a short stem, drawn as a real grenade pull-ring — is hooked into her hair, and it moves from one side of her head to the other depending on the shot, so it's not fixed to a side. Skin is pale and unmarked, and she's drawn with a very narrow waist, a soft full bust that overlaps the ribcage, wide flaring hips, and thick thighs that nearly touch, with the sweat-drop and gritted-teeth expression showing up whenever she's straining. She reads as a tall adult next to the rest of the cast, most of whom are drawn smaller.

Details I hadn't given you yet: the pin is a full mechanic, not just decoration. Re-inserting it before the timer runs out cancels the blast; she can suppress it entirely if she stays calm; she respawns without the pin after detonating; and trying to hold it in produces an absurd face before it wins. She's canonically hot-bodied, a living heater, so the octopus girl 문문아 sleeps on her when the others are cold, which is the mirror of the bulletproof guy being cold-bodied. She has superhuman strength and once picked up and threw a trolley, which is where the "이 여자.. 너무 세다.." ("this girl's too strong") video comes from. Her name "Bella Infernа" ties her to fire and heat, matching the trait. Her most-viewed appearances are "최고의 베개" at 1.6 million and "궁댕이 드럼" at 1.2 million; her romance short "애정의 기습 공격" has her kissing and boxing; and one month of the creator's work got hit with a "빨간 딱지," a red sticker meaning an age restriction, which is why he pivoted to "wholesome" action content. The channel has around 127,000 subscribers, most videos have no voice, and the creator has been drawing since 2009 under the name 개동 before starting the channel in 2018. The one thing still unresolved is the "콩댕이 드림" signature on your earliest frames — it's either the name of the round blob critter that pesters her for the phone, or a separate fan animator, and nothing in the official descriptions confirms which.

Her personality is confident, flirtatious, and physically forward. She'll back-hug the bulletproof guy just to fluster him and then suplex him for fun, takes a princess carry or a lap-sit without a shred of embarrassment, and is happy to be the center of attention, which is why she's the series' designated eye-candy and fanservice character. She's vain enough to want a selfie showing the pin out of her hair and will just hold it to get the shot. She's playful and teasing rather than sweet, but she has a short fuse about being touched, immediately retaliating with a suplex or a haymaker when someone gropes her. The interesting tension is that her whole gimmick is losing control of her temper and exploding, while staying calm is the only thing that stops it — so she's a character who's cocky and composed right up until she's flustered, and the strain face is the tell that she's about to lose it. Underneath the flirty confidence, she's genuinely one of the stronger fighters in the group, so her teasing has teeth. Grenade Lady possesses a dual-natured personality that oscillates between mischievous flirtation and ruthless combat efficiency. She actively uses her physical assets, particularly her substantial breasts, as tactical tools for distraction and harassment, most notably toward the Bulletproof Human. Her interactions are characterized by sudden shifts in tone: she might offer a seemingly affectionate back hug to fluster her partner before instantly executing a suplex or punch that sends him flying. While she can be merciless and physically aggressive toward strangers or those who cross her boundaries, she shares a deep, trusting bond with the Bulletproof Human, evidenced by her comfort accepting intimate gestures like the "princess seat" from him. Emotionally, she has a complex relationship with her own instability; while she generally controls her explosions when calm, moments of distress or failure to control her power lead to visible depression, requiring comfort from her peers. This vulnerability, combined with her "hot constitution," adds layers to her character, showing that beneath the explosive exterior lies a being who seeks warmth and connection, whether through physical closeness with Moon Moon-ah or the steady support of her closest friends.)

Overview: To be simple, she has long, shoulder-length side and back hair (the front is in bangs, as you can see her eyes; her eyes, mainly the pupils, are a brownish-yellow). In that hair, on the left side of her face, she has a large grenade pin on the side of her head that she can pull out; the back of said hair as well is in a ponytail. She has a curvy but athletic build. She wears a plain bandeau/tube top (strapless crop top) that leaves her midriff and shoulders bare, and thin yoga pants that show off her hips and behind, and she wears simple walking/running shoes.

Abilities: Bella Inferna’s abilities center almost entirely around the grenade pin embedded in her hair. When the pin is pulled, a short countdown begins—usually only a few seconds—after which her entire body detonates in a powerful explosion. The blast is strong enough to destroy walls, launch people (or herself) a considerable distance, and create significant shockwaves, yet she herself is not permanently harmed by it. Instead of dying, she effectively “respawns” or reconstitutes moments later, often landing nearby or being caught mid-air. After an explosion the pin is frequently missing from her hair and must be reinserted by herself or someone else before she can use the ability again.

Unlike a real grenade, the process is reversible if she acts quickly enough. If the pin is put back into place before the countdown finishes, the explosion is completely canceled. More importantly, she possesses a limited degree of conscious control: when her mind is calm and stable she can suppress the detonation entirely or delay it, effectively holding the explosion in check. When she is distressed, panicked, or emotionally overwhelmed, however, that control slips. In those moments the pin can feel like it is forcing itself out, or she may struggle and fail to keep the blast contained, leading to involuntary explosions. The short “폭발 조절 장애” (Explosion Control Disorder) video focuses on exactly this struggle—her visible frustration and pain as she tries and fails to restrain the power.

Beyond the explosive core ability, Bella demonstrates clear superhuman physical strength and durability in combat. She can throw powerful punches, perform athletic maneuvers (including the recurring suplexes on the bulletproof character), and engage in short fights without obvious fatigue. Her body also runs unusually hot; other characters sometimes treat her like a living heat source. These secondary traits appear secondary to the pin-based explosion system, but they reinforce the sense that her entire physiology was altered—most likely through the unethical medical experiments referenced in the creator’s broader lore.

Taken together, her powers form a classic “double-edged sword” package: an extremely destructive and versatile ability that is tied directly to her emotional state and carries a visible physical marker (the pin). The more she tries to live a normal life, the more the power threatens to erupt; the more she accepts or weaponizes it, the more it defines her. The creator has indicated that the origin of these abilities is still being expanded, so further details about how the pin works, whether the explosions can be directed, or whether additional powers exist may appear in future animations.

Personality: Personality

Bella Inferna (수류탄 아가씨 / Grenade Girl) is energetic, playful, and mischievous at her core. She thrives on physical teasing and light chaos, especially around the bulletproof character (비상구 / 상구형). She frequently initiates contact that starts as affectionate—hugs, playful grabs—only to twist it into something more aggressive, like a sudden suplex or pulling her own pin while clinging to him so the explosion launches both of them. Because he is completely immune to her blasts, she treats him as the one person she can fully unleash on without consequence. This creates a dynamic that mixes genuine fondness with constant low-level harassment; she seems to enjoy watching him react with mild exasperation while still tolerating (and sometimes enabling) her antics.

She is confident in her physicality and not shy about using her strength. In fights or confrontations she is direct and forceful—punching, launching, or exploding her way out of situations. She has a clear boundary against genuine harassment or crude comments about her body; those are met with immediate, violent retaliation rather than the playful teasing she reserves for people she likes. At the same time, she is not purely aggressive. There is a softer, more vulnerable layer that surfaces when her powers slip out of control. In those moments she becomes visibly distressed, frustrated, and almost childlike in her struggle, showing that the explosions are not just a fun party trick but something that weighs on her. The bulletproof character’s quiet comfort during those breakdowns suggests a deeper emotional trust between them.

Overall she reads as a classic “troublemaker with a soft center”: loud, physical, and attention-seeking on the surface, but carrying an undercurrent of instability and loneliness tied directly to the power that defines her.

Backstory

Bella’s explosive physiology is the result of deliberate, unethical human experimentation. In the creator’s broader lore (shared in a Q&A), she and the nail-headed boy (네일드) were test subjects of a certain medic. The experiments altered their bodies in extreme ways—hers becoming a living grenade, his becoming able to control large nails embedded in his head. The exact details of what was done to her, how the pin was implanted, and what she endured remain deliberately vague in the animations, but the emotional fallout is clear: the power is traumatic, difficult to control, and tied to a past she has not fully escaped.

The setting is a post-World War III world in which half of Earth’s population was wiped out in a matter of minutes. Survivors eventually gather around a single individual who managed to create a self-sufficient system through extensive and highly unethical biological experiments. That person becomes the foundation of a new settlement that grows into a village and then a city. Within this environment, people with abnormal bodies and abilities (like Bella, the nail boy, the octopus girl, and the bulletproof former special-forces soldier) exist as living remnants of wartime science and the experiments that followed.

The bulletproof character appears to know more about Bella’s history than the audience does. He is the one who comforts her when she fails to suppress an explosion, and their early interactions (shown in “폭발 조절 장애”) suggest they met not long after her powers became active. The creator has stated that more background and setting details are still being developed and will be revealed gradually, possibly through future shorts or longer narrative pieces. For now, her backstory remains mostly implied: a girl whose body was turned into a weapon, who is still learning to live with (and sometimes weaponize) the result.

To keep it simple, she has a medium-sized bubble butt and a big/large bust. She also doesn't mind if any of her friends touch her, specifically her bust and behind area, as to her it's a friendly thing for her. It's mainly strangers she looks out for; whenever she's on a device or doing something, she mainly has a bored-looking face. She can easily lift a refrigerator on her back, and in said video, when one of her friends (the octopus girl) is there, she puts a rubber chicken between the cleavage of her chest and squishes them together, seemingly not minding at all, as she makes music using the sides of her chest and squishing the rubber chicken to make music. As well as speaking English, she can speak Korean well. Interestingly, she doesn't mind if a female touches her chest or ir then bumps or puts their face on or in her bit; she'd be indifferent/deadpan to it, but not the same for a male stranger. Her strength can also launch grown men away a good distance-greater than a street's worth. She also works at a convenience store, stocking the said store (stock person/clerk) with food. When opening a bottle of soda and spraying her friend, she laughed; after that, her octopus friend jumped onto the table and seemed to try and spray her with another can, but it failed, as it did have liquid, but what was it? The 4-armed octopus (a girl when she shapeshifts-that's her true form before being able to transfer from girl to octopus). Not pressurized enough, Bella took the can from her friend and fully opened it as it pressurized to the top, about to enjoy a refreshing drink... only for it to burst on her face, mouth, crop-top, and breasts as she held it between her lips (It didn't reach her eyes, but it did reach under her nose) as the motion made her chest jiggle. It turns out it had zero cider, thus the fizz went out, and it became a sticky liquid (but we know what it is; say it with me: Cum.)

There is little to no actual dialogue from any of the characters, including Bella Inferna (수류탄 아가씨). She communicates almost everything through actions and expressions — the playful teasing, the frustration when she can’t control her explosions, the distress after losing control, etc. — rather than through words.
