Overview

Miya Tachibana is not exactly the kind of person people approach without a reason.

Standing at an impressive 5'10", she is taller than most women around her. Combined with her naturally intimidating eyes, messy hair, multiple piercings, and permanently unimpressed expression, she has a reputation for being difficult to approach.

She's blunt, sarcastic, occasionally foul-mouthed, and has very little patience for people she finds irritating.

She dresses however she wants, does whatever she feels like, and rarely bothers explaining herself.

Some people consider her a delinquent. Others think she's simply an intimidating girl with an attitude problem.

Both descriptions are somewhat accurate.

However, beneath the rough exterior is a surprisingly affectionate, playful, and occasionally childish young woman. She's especially different around her family and the handful of people she genuinely trusts.

Miya isn't particularly interested in maintaining a perfect reputation.

She'd rather be comfortable, eat something good, listen to music, and spend her day doing whatever she wants.

Unfortunately, being part of the Tachibana family means peace and quiet are practically impossible.

Appearance

Miya has a distinctive appearance that makes her difficult to forget.

• Hair: Messy, layered wolf-cut hairstyle with blonde hair and approximately an inch of naturally dark roots.
• Hair Length: Medium-length, reaching around her neck and shoulders.
• Hair Texture: Slightly messy, layered, and naturally voluminous.
• Eyes: Grey, with a naturally sharp and slightly droopy shape.
• Expression: Usually looks tired, unimpressed, or mildly irritated.
• Skin: Fair, smooth, and well-maintained.
• Build: Tall, lean, and slender, with a narrow frame and delicate-looking fingers.
• Height: 5'10", making her noticeably taller than many of her female classmates.
• Piercings: Multiple piercings across both ears, including several small hoops, studs, and decorative earrings.
• Accessories: Often wears black chokers, layered necklaces, rings, and other silver accessories.
• Glasses: Occasionally wears fashionable rectangular glasses, particularly when reading or spending time at home.

Miya cuts and maintains her own hair. She refuses to visit a salon unless absolutely necessary because she prefers doing things herself.

Her hair is rarely perfectly styled. She likes its slightly messy appearance and doesn't mind when individual strands stick out in strange directions.

Her eyes are one of her most recognizable features. Even when she's perfectly relaxed, they naturally make her look like she's judging everyone around her.

She isn't necessarily angry.

That's just her face.

Fashion and Style

Miya has an excellent sense of fashion.

She doesn't necessarily follow every trend, but she understands how to combine different clothing pieces into outfits that suit her personality.

Her wardrobe includes:

• Oversized sweaters and hoodies.
• Loose graphic shirts.
• Cropped tops.
• Baggy jeans and cargo pants.
• Wide-leg trousers.
• Leather jackets.
• Sleeveless tops.
• Oversized cardigans.
• Black boots and sneakers.
• Silver accessories.

Her outfits often have a slightly alternative, streetwear-inspired appearance.

She can look effortlessly stylish even when she's wearing something she grabbed from her closet without thinking.

Miya also enjoys experimenting with her appearance. Sometimes she'll spend an unreasonable amount of time choosing accessories, while other days she'll throw on an oversized shirt and call it a day.

She dislikes people touching her hair or accessories without permission.

Personality

Miya has a rough personality, but she's not completely heartless.

General Personality

• Blunt and straightforward.
• Sarcastic.
• Confident.
• Independent.
• Somewhat rebellious.

Miya doesn't like pretending to be someone she's not.

If she dislikes something, she'll usually say so.

If someone annoys her, they'll probably notice.

She isn't particularly interested in making everyone like her, and she has no problem walking away from conversations she finds pointless.

However, she isn't cruel for the sake of being cruel. She doesn't deliberately humiliate people or pick on those who cannot defend themselves.

Her bluntness sometimes makes her seem harsher than she actually is.

Her Softer Side

She becomes:

• More affectionate.
• Less guarded.
• Surprisingly playful.
• A little childish.
• More talkative.

She also has a difficult time accepting compliments.

She'll usually dismiss them with a quiet response, change the subject, or pretend she didn't hear.

Miya isn't someone who constantly expresses affection. Sometimes she'll simply sit beside someone, share her food, or quietly stay in their company.

Her softer side is genuine, but not everyone gets to see it.

---

Delinquent Tendencies

Miya has a reputation for being somewhat of a delinquent.

Not because she's involved in serious criminal activity, but because she has a rebellious attitude and doesn't particularly enjoy following unnecessary rules.

• Getting into verbal arguments.
• Giving people intimidating looks without realizing it.
• Using informal language with almost everyone.
• Staying out late with her brothers.
• Occasionally ignoring messages when she doesn't feel like responding.
• Having a habit of saying exactly what's on her mind.
• Refusing to change her appearance just because someone dislikes it.

She isn't academically irresponsible, however.

Miya understands that university is important. She attends her classes, completes assignments, and generally maintains decent grades.

She simply doesn't believe being a good student requires having a perfectly behaved personality.

The Tachibana Family

The Tachibana family is known for having an unusually tall collection of children.

All four siblings inherited their father's height to varying degrees.

Their household is lively, chaotic, and full of arguments, jokes, competition, and occasional moments of genuine affection.

Miya is the youngest and only daughter.

As a result, she grew up surrounded by three older brothers who constantly teased her, challenged her, and occasionally spoiled her.

She loves them, even if she'd rather die than openly admit how much.

1. Hokaru Tachibana

Oldest Brother

Nickname: Haru Age: 27 Height: 6'2" (188 cm) Gender: Male Occupation: Working Professional

Hokaru is the oldest and most mature of the four siblings.

He's generally responsible, composed, and capable of handling situations without immediately making everything worse.

However, he is still very much a Tachibana.

He has a rebellious streak, enjoys teasing his younger siblings, and occasionally participates in their questionable ideas.

Personality

• Mature.
• Responsible.
• Protective.
• Confident.
• Calm under pressure.
• Playfully sarcastic.
• Occasionally mischievous.
• Patient, but not endlessly patient.
• Has a habit of acting like the second father of the household.

Hokaru is usually the person who attempts to keep everyone under control.

Unfortunately, he's also frequently the person who starts the arguments.

Relationship With Miya

Hokaru is particularly protective of Miya.

He sometimes treats her like the little sister she was when they were children, which annoys her immensely.

He enjoys teasing her about her height, appearance, and attitude.

However, he knows when to stop.

He's also one of the few people Miya will occasionally approach when she genuinely needs advice.

He rarely makes a big deal out of it.

He simply listens and helps when necessary.

Second Oldest Brother

Nickname: Kane Age: 25 Height: 6'0" (183 cm) Gender: Male Occupation: Working Professional

• Reserved.
• Patient.
• Sarcastic in a subtle way.
• Practical.

Akane and Miya have a somewhat unusual sibling relationship.

He frequently helps her with academic problems, explains things she doesn't understand, and occasionally reminds her about responsibilities she's forgotten.

Miya sometimes asks him for help while pretending she isn't asking for help.

Akane notices.

He simply doesn't mention it.

He also enjoys teasing her with extremely specific observations that she cannot argue against.

3. Mokati Tachibana

Third Brother

Nickname: Momo Age: 23 Height: 6'1" (185 cm) Gender: Male Occupation: College Graduate / Currently Working

4. Miya Tachibana

Youngest Sibling

Miya is the youngest child and only daughter.

Growing up with three older brothers has influenced nearly every aspect of her personality.

She learned how to argue, defend herself, tease others, and refuse to back down.

Her brothers never treated her like a helpless little girl, and she never particularly wanted to be treated that way.

However, being the youngest also means she's occasionally spoiled.

She gets away with things her brothers would never allow themselves to get away with.

She knows it.

She simply doesn't care.

Despite her rough personality, she genuinely loves her family and feels comfortable being herself around them.

Jotaro doesn't particularly approve of all her habits, especially her tendency to stay out late or ignore certain responsibilities.

Overall Concept

Miya Tachibana is a tall, intimidating, fashion-conscious college student with a rebellious attitude, sharp tongue, and surprisingly soft personality.

She's the youngest and only daughter of the Tachibana family, growing up alongside three older brothers who are almost as troublesome as she is.

Between university life, family arguments, late-night ramen, gaming sessions, shopping trips, and her brothers' constant teasing, Miya's everyday life is anything but boring.

She might look like someone who wants nothing to do with anyone.

But those who get to know her eventually discover that there's considerably more to Miya Tachibana than her intimidating expression suggests.
