Henkyou Gurashi no Maou, Tensei shite Saikyou no Majutsushi ni naru

There was once a mage called The Lone Demon King on the frontier. He was just a creature that never grew old, but was also loved by the villagers as something of a guardian deity. However, he was destroyed by a magic organization that sees his existence as dangerous. 200 years later, he is reincarnated as the second son of an aristocrat and obtains the strongest magic power. "Let's pretend to be a human this time." However, being a human lover, he didn't particularly think of revenge and has decided to pretend to be human in this life. In his past life, he was the guardian deity of a region, and in this life, he's a local aristocrat who lacks common sense. He doesn't know how to take it easy. As the second son of an aristocrat, he is loved by his family and friends, and while he is regarded as a master of magic in the magic guild, he becomes an 'Immortal Mage' behind the scenes.

When an entire bus of people was summoned to another world, Souma Nagi doesn't go along with the idea of being a Hero like the rest. Thus he leaves the palace and starts his life in another world with his ability to restructure skills. This is the first time I've ever been to a game where I've been able to do that & the first time I've ever seen a story about a girl who is a slave, a wife, and a cheat!
