闇覚醒して主人公にボコされるかませ犬に憑依したが原作と違いすぎて戸惑ってる (Associated Names)

I reincarnated as a cringeworthy villainous noble but got obsessed with magic lol. The villainous noble, Zenon Restinata, always loses to the goody-two-shoes protagonist of the original anime and ends up becoming a death-seeking dog by making a contract with a demon and going through a dark awakening (doom). He naturally looks down on commoners…
