Synopsis

Soujirou Katsuragi (aged 38) died of illness, but instead he's transported to another world!? A goddess who takes pity on Soujirou, who is inherently unlucky and has no experience with women, grants him blessings before his reincarnation. He wishes for "a healthy body, I don't need any special powers," but instead receives two blessings: immortality and a strong jaw. What? Isn't that a cheat ability? Attacked by catastrophic monsters, getting into trouble with thugs at the guild... In short, the adventure of this unlucky but cheat-powered old man begins!
