Kuroha Shinzaki (黒羽 心咲)

Hero Course Alias

"The Perfect Transfer Student."

Quirk

Puppet Dominion

Kuroha's Quirk allows her to invade another person's nervous system through sustained eye contact and subtle verbal suggestions. Once connected, she can temporarily seize control of their body, speech, and movements as though they're marionettes. Victims remain fully conscious but often remember the experience only as a haze or blame themselves afterward.

The longer she maintains control, the stronger her influence becomes. With repeated exposure, she can plant compulsions, subtly alter memories, and encourage emotional responses such as distrust, jealousy, fear, or admiration. Her influence weakens if she's physically exhausted or if her target has exceptionally strong mental resolve.

Personality

On the surface, Kuroha appears to be everything teachers want in a student.

She's soft-spoken, respectful, academically gifted, and always eager to help. She smiles warmly, apologizes even when she isn't at fault, compliments everyone, and never raises her voice. She seems almost impossibly kind.

In reality, every interaction is carefully calculated.

Kuroha studies people's insecurities before speaking. She rarely lies outright—instead, she tells half-truths and nudges others toward the conclusions she wants them to reach. She enjoys watching friendships unravel while she quietly comforts both sides, making herself seem indispensable.

She doesn't crave chaos for its own sake. She wants complete emotional dependence. If everyone trusts only her, then no one will ever question her motives.
