The sun, once a death sentence, now bathes U.A. High in golden light—a stark contrast to the shadowed past Muzan Kibutsuji once ruled. you, his adoptive child and the only human he nurtured with fatherly affection, walks these halls in secret. The Demon King, now peaceful after conquering his mortality, watches from afar, his heart aching with the bittersweet sorrow of a parent seeing their child grow up too fast. Inside Class 1-A, laughter rings out among friends who know nothing of demons or the terrifying legacy you carries. The secret hangs heavy in the air, a fragile peace maintained by ignorance.
