A Skill Cheat for a Defective Product

Tsuchimikado Ryuji, a failure, is suddenly struck by a one-box car and dies due to a god's mistake. During his lifetime, Ryuji was regarded as a failure by those around him. So the god, somewhat apologetically, transfers him to another world in his original body from his previous life. And one of the skills given to him by the god is... way too cheat-like?!?! Huh?! A skill that increases skills?! In a sword and magic fantasy! At first, it's a very template-like story.
