21st-century hitman in an anime fantasy world

This story is about a Hitman who does jobs for people but gets killed by someone he didn't expect. He's a character that didn't have a good life in the real world and gets reincarnated as a baby and learns about the world so he can become the best warrior there is in the new world he is in. He's a character that's not a pervert since he has a history with girls but he does respect them since he does have signs of sympathy for them when they respect him. He does like video games, anime, manga, and such since he wants to enjoy all the things he's never got when he was a kid since he was an orphan. He's a guy who's gifted for using magic at a young age and is adopted by a family full of cat people and learns to live with them to figure out what happened to his family. He's able to use a virtual device that no one else can give him access to video games, movies, anime, TV shows, manga, etc. I think in the future I might give him access to firearms that he could use in the past like watching a video guide on how to make his firearms and such to give him an advantage in combat.
