In this episode, the battle against Lycagon, one of the mighty Seven Colossi, continues. The group devises a strategy centered around Psyger-0's powerful finisher, which can only be activated once certain hit conditions are met and a lengthy incantation is completed. While Psyger-0 prepares the spell, Sunraku and the others defend him against Lycagon's relentless attacks, particularly the invisible shadow clones that strike unexpectedly.

Akitsuakane employs a specialized ninja technique to reveal hidden threats. This allows Ceecrue to land precise attacks. Meanwhile, Sunraku unveils a risky and powerful ability that converts stored moonlight energy into a massive wave of damage—an option so potent that it inflicts severe recoil damage on the user.

Finally, Psyger-0 completes the complex incantation and unleashes a stunning attack called "Armageddon." At first, the group believes they have won the battle with this ultimate strike. However, it turns out their opponent was merely a projection of Lycagon, not the true Colossus.
