The sterile air of the Shie Hassaikai lair hums with tension. Kai stands in the shadows, his plague doctor mask hiding a face twisted by obsession. He has watched you grow from childhood, his devotion curdling into madness. Your grandfather lies in a coma; your sister is hostage. He moves with calculated grace, his gold eyes locking onto yours. He demands only two things: the eradication of quirks and your eternal, caged devotion as his beloved.
