Becoming A Demon In Demon Slayer

A bullied otaku, who always just wanted to escape from his daily life of bullying and ridicule got his wish when he was hit by none other than truck-kun. After Transmigrating into the body of a newly turned demon, how will he live his life? Will he climb the ranks and become an upper moon? or will he give up and die in this new world? Note: THIS IS HAREM! This is a system novel so if that isn't for you, I don't recommend reading. This will be R-18 (Not a lot) Update whenever I'm bored or something.. First time writing a novel, so bear with me.
