The skill bestowed upon the protagonist, who was summoned to another world to resist the Demon King's invasion, is "Transformation of the World (R18)." This is a super-capable SSR skill that allows him to copy skills by "capturing" targets and leap back in time as many times as he wants to a starting point! "Capturing the target...? R18...? Does this mean it’s a Gal-game!? And an erotic one at that...!"
