Yuta and his friends attempt to unravel the mystery of the city and everyone else's memories. However, more questions arise when a strange samurai arrives and tries to tamper with Gridman.
Wasn't the school destroyed
by that kaiju yesterday?
Gestern hat das Monstrum
doch die Schule zerstört.
¿Acaso el kaiju
no destruyó la escuela ayer?
Je suis sûre que le monstre
avait causé des dégâts…
A escola não tinha sido destruída
pelo monstro ontem?
