Soujirou Katsuragi (died at age 38) was supposed to have passed away from an illness, but found himself in another world!? Taking pity on Soujirou, who has an inherently unlucky constitution and on top of that, zero experience with women, a goddess decides to grant him divine protections before his reincarnation. When he requested, "I don't need any special powers, I just want a healthy body," the two protections he received were [Immortality] and [Strong Jaw]. Eh? Wait, aren't those cheat abilities? Being attacked by natural disaster-class monsters, getting picked on by thugs at the guild... He is incredibly unlucky, but the adventure of this cheat old guy begins!!
