I Possessed the Underdog Who Awakens to Darkness and Gets Beaten up by the Protagonist, but I'm Confused Because It's Too Different from the Original Work, I Reincarnated as a Villainous Noble Fated to Lose, but Got Obsessed with Magic, The Story of the Dark Awakening of a Bait and Switch Dog, 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

Synopsis Yami Kakusei Shite Shujinkou ni Bokosareru Kamase Inu ni Hyoui Shita ga Gensaku to Chigaisugite Tomadotteru

The villainous noble, Zenon Restinata, is a disappointing “underdog” who gets beaten up by the protagonist in the original anime. “I,” a mere fan of the original work, have possessed such a Zenon!? This place is completely the world of the anime, and when I tried out magic for starters, it was super fun. I've decided– I'm going to change Zenon's disappointing ending! The “do-over” life of a magic maniac begins!!
