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.
And we've been living
right next to them for so long...
Dabei wohnen wir die ganze

por tanto tiempo...
On a vécu toute notre vie
dans cet endroit…
E estivemos vivendo tão
próximos deles esse tempo todo...
