Mazoku-Jun is a great person kind, ruthless, and understanding...For a fictional demon emperor! Mazoku-Jun is from a very popular book called the Rising of the Winter Storm or TROTWS. A character who Hajime Yami loves very much, his brother Hikari Yu or Yue xinghuo baihe, is the author. Yami always wanted to meet Mazoku-Jun, but knew it was impossible...Until Yami suddenly dies while re-reading TROTWS. He finds himself transmigrating into TROTWS!!!...As the villain nonetheless! The worst part is that his system is a sack of shit! "Curse you, System!!! I want a refund or at least some OP weapon, because this just isn't fair!!.."
