I was Reincarnated as a Grossly Fat Villainous Noble in an Eroge Full of Villains. I'll Lose Weight, Avoid Ruin, Prevent the Villains' Crimes Before They Happen, and Live a Slow Life.

Karl de Hamilton is a disgusting villain aristocrat who appears in Extreme Eroge. Because of his terrible appearance, most people hate him, and he lives a lazy and withdrawn life. Okay, since I've been reincarnated, let's train our bodies and lose weight for the time being. Not only me, but also other terrible-looking friends (villainous young lady) are invited to go on a diet together! In order to avoid the ruin flag of being killed by the main character, try not to get involved with the main character as much as possible and aim for a slow life! There are many villains other than me, so destroy the scenario so they don't do anything wrong! Oh, why do the main characters, SS-class heroines, care?
