Badass obese prince and his harem of anime babes

Luciel was a good man, after he died, despite not being able to choose the world where to reincarnate, he can still choose to have a badass physique that was strong without having to train and a system to summon hot babes..... .but he had a sin in his life, bullied a fat guy at school and was sentenced to be obese in his new life (the protagonist is literally the protagonist of the story, but in the world where he goes, there will be other "protagonists", this is not a serious work)
