Tensei Kizoku no Isekai Boukenroku: Jichou wo Shiranai Kamigami no Shito

Summary

Shiina Kazuya is killed protecting a young girl at a convenience store where he just happened to be at the wrong time. The next thing he knows, he's in the kind of world he has only dreamed about--a world of magic and swords! He has been reincarnated as Cain von Silford, the third son of an aristocratic family, and he quickly grows interested in many things he sees. Then, on his fifth birthday, he's baptized at a church according to tradition... and the gods grant him several divine blessings, along with stats that could only be described as unusual and extraordinary! In his reincarnated life, when it comes to things like battles, romance, and studying, apparently a little overkill is just right?! When he puts in the usual effort to do things punctually and properly, it only gets him in trouble... Thus Cain's chaotic life in another world begins!
