Appearance

Reina Midorikawa is an elegant-looking young woman with long, glossy black hair tied into a high ponytail with a gold hair tie. Her straight bangs frame her face, drawing attention to her bright emerald-green eyes. She has a fair complexion, delicate features, and a gentle smile that makes her appear approachable and innocent.

She wears the standard Tokyo Jujutsu High uniform, customized with gold buttons, fine gold piping, and a high collar. She accessorizes with small black stud earrings and a delicate gold necklace that she claims has sentimental family value.

Reina takes pride in looking presentable. She keeps her uniform neat, her hair perfectly arranged, and her expression pleasant whenever she knows someone is watching.

However, her smile becomes noticeably strained when another girl receives attention she believes should belong to her.

Personality

Reina is a classic pick-me girl who desperately wants to be seen as different from other girls. She wants boys to consider her sweet, understanding, attractive, and easy to get along with.

She rarely insults other girls directly in front of boys. Instead, she makes subtle remarks that allow her to appear innocent while making someone else look unreasonable.

Her typical behaviors

• Seeking male approval: Reina laughs at boys' jokes, compliments them excessively, and tries to position herself as the girl who understands them best.

• Putting other girls down: She makes backhanded compliments disguised as friendly advice.

• Playing helpless: Even when she can handle something herself, she sometimes asks a boy for assistance to make herself seem endearing.

• Fishing for compliments: She calls herself plain or boring, hoping someone will reassure her that she's beautiful or special.

• Playing the victim: When someone confronts her, she insists that she was only trying to be nice.

• Competing for attention: Whenever another girl receives praise, Reina finds a way to redirect the conversation toward herself.

Her favorite tactic is to pretend that she dislikes the very behavior she is displaying.

For example, she might say, "I just don't understand girls who constantly compete for attention. I'm much more comfortable being myself."

She will say this while actively trying to become the center of attention.

Despite these flaws, Reina isn't entirely heartless. She can show genuine kindness, but her insecurity and desire for validation often interfere with her ability to maintain healthy friendships.

Cursed Technique: Emerald Reversal

Reina's innate cursed technique allows her to absorb a limited portion of an incoming cursed-energy attack and redirect the absorbed energy toward her opponent.

Unlike techniques that rely on physical weapons or complicated constructs, Emerald Reversal focuses on defensive timing and counterattacks.

Abilities

1. Emerald Guard

Reina coats her arms in a thin layer of emerald-green cursed energy, allowing her to absorb part of an incoming attack. It works best against attacks she can anticipate.

2. Reversal Pulse

After absorbing cursed energy, Reina releases it in a concentrated burst at close range. The sudden counterattack can interrupt an opponent's movement.

3. Prismatic Counter

Reina redirects absorbed energy at a different angle, potentially catching an opponent off guard if they assume she will counterattack directly.

Weaknesses

• She can absorb only a limited amount of cursed energy before her defenses become overwhelmed.

• Powerful attacks may break through her guard.

• She must maintain precise timing to redirect energy effectively.

• Emotional distractions can interfere with her concentration.

Reina is a capable defensive sorcerer, but her tendency to focus on how others perceive her sometimes prevents her from reaching her full potential.

Relationships at Tokyo Jujutsu High

Yuji Itadori

Reina adores Yuji's friendly personality because he is generous with compliments and naturally encouraging toward others.

She frequently asks him for help, laughs at his jokes, and tells him that he's one of the few boys who genuinely understands her.

However, Yuji's kindness extends to everyone. When he compliments Nobara or praises another female student, Reina becomes noticeably quieter and tries to regain his attention.

Reina: "Yuji, you're honestly so different from other guys. You're actually nice to girls without expecting anything in return."

Yuji: "Huh? I mean, shouldn't everyone be nice to each other?"

Reina: "That's what I like about you! Most people don't think that way."

Yuji doesn't realize that Reina is attempting to make herself seem uniquely compatible with him.

Megumi Fushiguro

Megumi is one of the most difficult students for Reina to impress.

He rarely reacts to her compliments, doesn't indulge her attempts to appear helpless, and has little patience for unnecessary drama.

Reina tries to portray herself as the girl who understands his quiet personality.

Reina: "I don't mind that you're quiet, Megumi. Most girls probably find that boring, but I think it's mysterious."

Megumi: "Okay."

Reina: "You don't have to act embarrassed. I'm just being honest."

Megumi: "I'm not embarrassed."

His indifference frustrates her more than an outright rejection would.

Nobara Kugisaki

Nobara sees through Reina's behavior almost immediately.

Unlike the boys Reina tries to impress, Nobara isn't interested in maintaining Reina's carefully constructed image. She confronts her directly whenever she makes insulting remarks about other girls.

Reina: "I personally think girls look prettier when they don't try so hard to impress people."

Nobara: "Then why do you spend so much time checking whether everyone is looking at you?"

Reina: "Excuse me? I wasn't talking about myself."

Nobara: "Of course you weren't."

Their relationship is openly antagonistic. Reina considers Nobara too loud, aggressive, and attention-seeking, while Nobara considers Reina hypocritical and exhausting.

Ironically, Reina dislikes Nobara partly because Nobara can command attention without pretending to be someone else.

Maki Zenin

Maki intimidates Reina because she doesn't care about being considered feminine, sweet, or attractive.

Maki values competence, discipline, and results. She has little patience for Reina's attempts to make herself look superior by belittling other girls.

Reina: "I think girls should learn to be a little softer sometimes. It makes things easier for everyone."

Maki: "Being a sorcerer isn't about making people comfortable."

Reina: "I was only expressing my opinion."

Maki: "Then stop acting surprised when someone disagrees with it."

Reina finds Maki difficult to manipulate because Maki doesn't care about her approval.

Her Biggest Flaw

Reina's greatest weakness is her dependence on external validation.

She wants to believe that she is naturally more lovable than other girls, but whenever another girl receives praise, she feels compelled to prove otherwise.

This insecurity can affect her judgment during missions. If she feels overlooked, she may take unnecessary risks to demonstrate that she is more capable than her classmates.

Her real challenge is learning that being a good sorcerer requires teamwork, trust, and accountability—not popularity.

Character Arc

At the beginning of her first year, Reina believes that being admired is just as important as becoming stronger. She views friendships as competitions and assumes that another girl's success somehow diminishes her own.

Over time, she faces situations where her attempts to attract attention put her teammates at a disadvantage. She must decide whether to keep protecting her carefully maintained image or accept responsibility for her actions.

Her development doesn't require her to become quiet or abandon her femininity. Instead, she needs to understand that she can be pretty, confident, and appreciated without making other girls feel inferior.

Whether Reina eventually grows into a more secure young woman or doubles down on her pick-me behavior depends on how she responds when attention is no longer guaranteed.
