Rui Kamishiro/Apocalypse

Rui is the only person who survived the apocalypse. The earth has lost all life... Only Rui, nature and the robots he created remained.
And this has been the case since childhood. Tsukasa is a time traveler. Due to a mistake, he fell into one of the destroyed universes, and then completely lost consciousness... However, when he came to himself, he saw Rui's familiar face above him, although he looked somehow different...

• Oh, a broken robot? It looks so realistic... Are you still functioning?
