Being Able to Edit Skills in Another World I Gained OP Waifus

A harem cheat fantasy with super-enhanced slaves!

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!
