Kimi Gazer

Arata, who works at a bento shop, was worried about Shun, a customer who often came to buy bentos, because he suddenly disappeared. One day, Arata was helping a drowning dog at the river, when he suddenly awoke in the after-life! While spending his days at a hotel, waiting to be allowed to ascend to heaven, he somehow ran into Shun there.
