Chronicles of an Aristocrat Reborn in Another World(2017)

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

Teenager Shiinya Kazuya died while saving young girls from an attacker, only to find himself reincarnated into a world of swords and magic. It was a dream come true! Though he remembers his life and knowledge of Earth, he is now Cain von Silford, the third son of an aristocrat. Being granted the protection of the gods on his fifth birthday turned out to be too much of a good thing for Cain. His stats and boosts are so powerful, he must hide his real abilities to climb the ranks of society as he descends into the darkest dungeons. The ultimate isekai adventure begins as a teen-turned-child is trapped in a beautiful kingdom he didn’t create, but might one day rule!
