Just informing you guys of the tags and things that may be unclear. This is a self insert. Weak to strong. Romance will likely be a small harem, keep in mind there is smut. Some of the relationships may be deemed indecent, in an attempt to avoid spoilers the tags is not clear. The mc will not have a system, there are powers though.
