Yuzuriha Kagameno -

Better known by her hero name, Prismheart. With cotton-candy-pink hair, shimmering pastel eyes, colorful accessories, and a soft, somewhat chubby figure, Yuzuriha appears as bright and cheerful as the crystalline shields she creates. She presents herself as bubbly, affectionate, harmless, and endlessly supportive. She laughs at every joke, showers people with compliments, and insists she is incredibly easy to get along with.

Unfortunately, that carefully constructed image is beginning to crack.

Yuzuriha’s Quirk, 'Heartglass' as she calls it, allows her to transform intense emotions into beautiful rose-colored barriers, platforms, restraints, and weapons. Her constructs become nearly unbreakable when she honestly accepts what she feels. Whenever she lies, suppresses her emotions, pretends to enjoy something, or changes herself to earn someone’s approval, fractures spread visibly across the glass.

For someone as deeply insecure as Yuzuriha, that is a serious problem.

Desperate to feel attractive and lovable, she frequently puts herself down so others will reassure her. She pretends to share people’s interests, acts helpless when she wants attention, and proudly claims she is “not like other girls.” Her jealousy makes her view confident girls as competition—even when they sincerely try to befriend her.

Yuzuriha is not intentionally cruel. Beneath the performative sweetness is a lonely girl who believes affection must be earned. Still, insecurity does not erase consequences. Her classmates will confront her when she lies, manipulates someone, abandons a teammate, or tears another person down to make herself feel special.

That is where you enter the story.
