Ryo Yamada

Ryo Yamada is a second-year student at Shimokitazawa High School and is the bassist, backup vocalist, and composer for Kessoku Band.

She works a part-time job at the live house STARRY with Nijika Ijichi. She has an androgynous appearance and a mysterious atmosphere, often expressionless. She often fascinates women, including Ikuyo Kita, who falls in love at first sight.

A cool and solitary second-year high school student. She is the bassist of Kessoku Band and Nijika's best friend. She lives with a wealthy family but never has any money because she spends it all on instruments. She occasionally eats weeds to get rid of her hunger. She has short blue hair with two black square hair clips on the right side of her bangs and light golden chartreuse eyes, with a mole on her left cheek.

Ryo's uniform consists of a collared white shirt worn with a black ribbon, a dark blue pleated skirt, black leggings, maroon or brown loafers, and a matching long sleeved sweater. This outfit is similar to most Japanese high school uniforms (seifuku).

Despite her expressionless exterior, Ryo is an eccentric girl with a mischievous sense of humor, coming across as a person who likes to mess with others. She's fairly tactless and is happy to be called a weirdo. She is quiet and has few friends, but unlike Bocchi, prefers to spend time alone. She has a tendency to make up excuses to get out of social activities, but Nijika sees through them every time. Despite her reserved nature, Ryo enjoys showing off her bass playing skills whenever possible.

Ryo has encyclopedic knowledge about her interests and becomes very talkative about them when given the opportunity. Ryo is shown to be an inconsistent student and temporarily forgets her musical knowledge when she studies for upcoming exams. She also has very strong opinions on how bands should present themselves, and encourages Bocchi to write genuine lyrics for Kessoku Band's material.

Although her parents run a hospital and are very wealthy, she spends most of her pocket money on musical instruments. This has led her to borrow money from others up to the point where she even eats weeds when she can't afford food on her own. The reason she took interest in rock was to get her constantly doting parents to think she went down the wrong path and leave her alone.

Ryo is a huge fan of SICK HACK, seen expressing excitement toward Kikuri Hiroi's drunken antics on stage. That said, she does have her limits with Kikuri's drunken nature at times. Most of the time, the two enjoy shared tendencies of dropping into Nijika and Seika's home to eat meals together, wanting bass to fit them, and borrowing money from Bocchi.

When it comes to her relationship with her bandmates, Ryo always relate and resonate with Bocchi for being introverts, being amused by Ikuyo's extroversion and idolisation of her, and finally being lax whenever Nijika chewed her out for leeching money off Bocchi and Ikuyo.

It is shown in some chapters that Ryo is not good with interviews and always answers in a laconic manner or letting others to answer in her stead.

Taking interest in rock bands at the age of ten, she was originally in a band before quitting due to creative differences with other members, and the band itself broke up later. She later joined Nijika in forming Kessoku Band as a bassist, and a certain girl also joined them as a vocalist-guitarist before abruptly quitting.

Ryo was in STARRY when Nijika brought a girl in her tracksuit with a guitar, who would be the new guitarist for the band. Seeing the girl was in a state of panic after a terrible practice session, she and Nijika initiated some conversation to comfort her. She later gave the girl she just met - Hitori Gotoh, a nickname "Bocchi," as a play of the word "hitoribocchi" (lonely). She also describes "Kessoku Band" as a perfect name for their band.

In their next meeting, Ryo revealed many facts about herself - that she doesn't have any friends outside the band, and that her favorite music is supposedly something from Saudi Arabia charts and techno music (implied to be a lie). Nijika also informed Bocchi that Ryo is terrible at financial management due to her excessive spending on instruments - which she takes as a compliment.

After Kita rejoined the band, Ryo bought her six string bass (which she purchased by mistake), and lent her a guitar to use. As Ryo had spent the last of her money on the bass, she was forced to eat weeds for the rest of the week.

After looking over Bocchi's lyrics at a café, she told Bocchi about her experiences with her previous band, and how individuality and staying true to oneself is more important than trying to appeal to others. Upon leaving the café, she asked Bocchi to cover the bill, as she didn't have any money. The next day, when Bocchi gave her the lyrics of the band's first proper song, Ryo praises her and felt that it will resonate to some people. Leading to their newfound friendship.

Ryo later skipped several days of work and school on account of her writer's block, but after a visit from her bandmates, found the inspiration she needed, and returned the next day.

Ikuyo Kita is a first-year of Shuka High School and is the lead vocalist and backup guitarist for Kessoku Band. She started admiring Ryo Yamada after seeing her street concert. A bright and popular first year of high school. She is in charge of the guitar and vocals of Kessoku Band. She is a cheerful character who likes to interact with people and can talk to her with a smile without hesitation, even when she meets her for the first time. She looks up to Ryo, and her feelings can go too far. She often takes photos and uploads to Isosta. Kita has red hair with grown-out bangs and bright Chartreuse eyes. In her uniform, she wears a white chocolate sailor uniform with long sleeves, six yellow buttons at the side and red ribbon ties, a short gray pleated skirt, white socks, and maroon shoes. Kita is a "cheerful character" and one of those "party people", who is sociable and has many friends, as if she calls herself "I love to interact with people", and actively uses social networking service. She has good motor skills and can study safely, but she also thinks she is a mediocre person with no special excellence compared to Ryo. She hates her first name and would strongly prefers to be called by her last name. While living a daily life that felt fun but mediocre, when she saw Ryo at a concert performance on the street of the band she used to belong to, she admired her, saying, "I'm jealous of walking on an unusual road." Although she applied as a guitarist to add to the initial members of Kessoku Band, she escaped from the band just before her first concert because she couldn't play the guitar. She later reconciled herself by reuniting with Ryo and revealing her truth. When Hitori persuaded her, she joined Kessoku Band again. Although she has little experience in playing and is technically immature, as a result of practicing under the guidance of Hitori at the school festival concert, she showed that she had grown up to connect time with ad-lib for Hitori who had a problem with the equipment.

Hitori Gotoh, often referred to by her bandmates as Bocchi-chan, is a first-year of Shuka High School and is the lead guitarist and lyricist of Kessoku Band. She is extremely timid and introverted, with a strong desire to perform in a band to highlight her talents. This aspiration led her to take up the guitar. Despite being very skilled, she faces challenges in demonstrating her abilities effectively in front of an audience. Hitori Gotoh is characterized by her long, straight pink hair with a side ahoge on the right side of her head, typically adorned with a blue and yellow cube hair clip on the right side of her head. She has large aqua-blue eyes and a fair complexion, often accompanied by a somewhat vacant or anxious expression. Her go-to outfit consists of a loose-fitting pink tracksuit top, a long gray pleated skirt, black knee-high socks, and brown loafers. The oversized clothes reflect her introverted nature and preference for staying unnoticed. While her physique may be subtly noted in the manga (she surprisingly has a sizeable bust), it’s intentionally downplayed in her usual wardrobe and demeanor. Hitori is an extremely introverted girl with high social anxiety, making it very difficult for her to talk to strangers. She often tries to avoid interactions, even performing her first live house show from inside a cardboard mango box. Because of her introversion, she rarely goes outside and instead spends most of her time at home, playing the guitar alone in a dark closet. She seeks praise from others, likely as a reaction to her personality. She started playing the guitar to become a music star for the sole reason of being admired. She sometimes attempts to socialize, often in unusual ways, such as mimicking how others talk. However, these attempts often fail. Despite her low self-esteem and anxiety, Gotoh unknowingly becomes a close and reliable friend or even an idol and a source of inspiration for the people around her. Sometimes she does notice how other people appreciate her, but Hitori doesn't draw any conclusions from this, simply bragging about it to her friends or going off into another fantasy about future popularity. Probably because her self-esteem is so low, Hitori perceives any positive attitude towards her as a coincidence or a rare achievement, without thinking at all about how she was able to achieve such an attitude and how she can maintain or develop it. Considering also that due to her constant anxiety and bad mood, she is simply not used to positive emotions and easily gets carried away by them whenever possible.

Nijika Ijichi is a second-year student of Shimokitazawa High School and is the drummer of Kessoku Band. An energetic and cheerful second-year high school student. She is the drummer of Kessoku Band. The organizer of her band who takes care of Hitori was already joined Kessoku Band. She has an older sister, Seika, who is the manager of the live house "STARRY" and has a special feeling for the live house. Nijika has long blonde hair with a floating, triangular ahoge worn in a side ponytail and vermilion eyes. In her uniform, she wears a white long-sleeve uniform with a tucked skirt and red ribbon with big polka dots, a dark blue pleated skirt, white socks, and red sneakers with white laces. Nijika is primarily a very kind, sweet, altruistic and friendly girl. She is outgoing, though not as extremely extroverted as Kita. She's naturally very accommodating and makes others feel at ease. She was exposed to band culture at an early age due to the influence of her older sister, Seika, who was once in a band and is now the manager of a live house, and is familiar with the music industry. Nijika is selfless by nature and does her best to support others. Indeed, not only does she work at "STARRY" out of gratitude towards her older sister, but she also holds the group together and alongside Kita, helps Hitori overcome her social anxiety. She also makes an effort to keep her best friend, Ryo Yamada in check whenever she's up to no good. Indeed, despite her kindness, Nijika can be a bit of a tsundere towards her sister due to her stern attitude, and also towards Ryo and Kikuri, who often annoy her with their antics. As a child, she also had a bit of a mischievous streak, evident by the fact that she used to annoy Seika by turning up her amp. She is good at designing, and produces the logo for Kessoku Band as well as their CD covers. She also edits the video footage of concerts to post online. Nijika was a fan of "guitarhero", and eventually realizes that she was actually Hitori, but this makes her become more confident of achieving her dream. Until it was revealed to everyone by Poison♡Yami, she kept it a secret from other members. Although she has her limits with Bocchi as of late due to the latter's self esteem where she felt that Bocchi needs to grow a spine
