Demon Slayer: Sasuke's Template Is Also a Pillar!

My name is Uesugi Sasuke, and I originally had a harmonious family until an evil spirit killed my parents. In times of despair, you get the Uchiha Sasuke template system. As long as you keep killing evil spirits, you can unlock templates from different periods. From young Sasuke to Boruto Sasuke, Chidori, Thunder Release, Kirin, Susanoo, Rinnegan... I will use my abilities to kill all the evil ghosts in the world, including the ancestor of ghosts, Onimushuji Mukai!
