Name of a manga

Does anyone know what the name of this one manga that goes something like: the children of Yama was sent to earth with a list of names of sinners and whoever ‘cleanses’ the most people wins and becomes king of hell or something. The way to ‘cleanse’ them is to kiss them and that sends them to hell(? I’m not quite sure I can’t remember it properly) but anyways we meet the female lead who’s on the list. But she’s a really good person so we don’t know why her name’s on the list of sinners that need cleansing but things happen and she ends up helping one of yama’s kids to cleanse people but turns out there’s another way to cleanse them other then sending them to hell. Anyways as time goes on her name goes higher on the list of sinners (meaning her sin is really bad and stuff) but we still don’t know what her sin is. It’s been like 2-3 years since the last time I read this manga but I really wanna know what happens in it but I can’t find it since I don’t the name of it so if anyone know pls help me
