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.
Besides us, nobody remembers
the kaiju or Gridman at all.
Niemand außer uns erinnert sich
an das gestrige Monstrum und Gridman.
Aparte de nosotros, nadie recuerda
al kaiju o a Gridman en absoluto.
Personne se souvient du monstre
ou de Gridman à part nous trois.
Além de nós, ninguém se lembra
do monstro ou Gridman, nem nada.
