Ep. 15: Shu faces turmoil over vaccine shortages and Hare's tragic death during a supply run.

Tennouzu students utilize Shu’s voids to improve their environment, but tensions rise as vaccine supplies dwindle and a blockade approaches. Rumors spread that Yahiro plans to implement a Void Ranking system to prioritize survival for those with stronger abilities, causing unrest despite Shu’s opposition. Encouraged by Tsugumi, Hare intends to confess her feelings to Shu but instead comforts him as he doubts his leadership. Later, Souta and other students with weaker voids ask to train, but secretly leave school to find supplies. Shu joins them, and they are ambushed by Daryl’s forces. Hare uses her void to heal Shu but is killed by a helicopter shot before she can heal herself. As the Apocalypse Virus crystallizes and destroys her body, an enraged Shu forcibly takes Inori’s void to defeat Daryl. Blaming Souta for Hare’s death, Shu beats him and declares he will become a ruthless king, betraying Hare’s wishes.
