That time I got reincarnated as a slime: Pola

Dude dies,losses his memories, and gets reincarnated as rimiru’s opposite. He is gonna have the same powers but like dark cuz opposites. There will be no harem. I’m only caught up with the anime so idk anything else. Please tell me if there are any errors in spelling or in plot. Might update once a week idk I’m just doing it for fun It’s just for fun so sorry if it doesn’t make any sense
