Ep. 6: Ai discovers Ulla's deadly power and Scar awakens a frozen child in Ortus
Ai witnesses Kiriko remove Ulla's visual restraints, causing her gaze to kill and resurrect victims as undead. Julie saves Ai from Ulla's attack, and a masked man reveals Ulla is Koroshiohake, embodying Ortus's dark nature. Kiriko admits to deceiving Ulla to protect her, hoping she remains the last human so her powers become irrelevant. Ai challenges this, citing Kizuna's fear, but Kiriko stands by his love for Ulla. That night, Ai tells Ulla the truth, which Kiriko confirms. Ulla accepts her reality and her inability to be friends with Ai, embracing her through Kiriko instead. Later, Ulla, Ai, Julie, and Scar visit Celica Hecmatika, a baby frozen in time. Kiriko explains Ulla's mother cursed humanity, granting power to Ulla but rejecting it in twin Celica. Scar touches Celica, awakening her from stasis. In the epilogue, Scar adopts Celica with Ulla's blessing. A mysterious youth watching them depart claims to be like Ai.
