The Ones Who Aspired to Be Gods (1x13)

:

With no news of the batteries to power up the lights, Rentaro and his forces are about to confront the advancing Gastrea in the dark when thousands of lanterns appear to illuminate the sky for them. Setienshi contacts Rentaro who soon realizes that it was her idea to hold a festival in the occasion and he orders the attack to begin. Rentaro and Enju's companions tear by the enemy formation to open a path for them to Aldebaran and the duo succeeds to implant the bomb inside its body, but it fails to detonate. Realizing that it needs a strong impact to make the bomb explode, Rentaro decides to sacrifice himself, knocking Enju uncounscious after bidding farewell to her.
