Goodbye! I'm Being Reincarnated! #1

Plot

Yuya Kamigasaki is living the life any high-school boy would dream of: he’s got a house to himself, classes he can sleep through, and a childhood friend next door who grew into a total babe. But when an otherworldly princess with looks to die for shows up in his room and asks him to become the hero that will save her people, how can a guy refuse? That is, until he realizes she’s asked him to get reincarnated, and plans to send him through the great cycle of death and rebirth herself!
