Peace has returned, and everyone is back to their normal lives.

However, Toshiki Kai is faced with an astounding situation.
The hero who saved everyone from the threat of Link Joker, Aichi Sendou, has vanished from the face of the planet.
On top of that, the memory of Aichi has even disappeared from people's memories...
