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.
If kaiju are appearing,
it's only natural aliens come next.
Wäre doch denkbar, nachdem schon

Après un monstre géant,
ce serait pas si étonnant.
Se monstros estão aparecendo,
acredito que aliens são os próximos.
