in this story, you will be Yoriichi(yes male reader). in this story, Lucifer(the king of hell) and Muzan are the same people, well after you did your 13th form of the sun-breathing Muzan(aka in this story Lucifer) grew fear of you. after your brother, kokushibo turned into a demon you and your little sister got fired from the demon slayer crops. (yes I added another sibling in my book). your little sister got sick and the cure for the sickness was for you to go to another country (where Alastor live) to find the plant that can cure your little sister. after you can to that country you have to find the plant but it was too late...your little sister passed away before you could get the plant(btw you were informed by the crow) you just felt guilty for not saving your sister on time. you have to wait for 1 month for you to go back (because your ship hasn't returned yet but you lived in a house where only travellers can use it) until you met a man name Alastor you both became good friends or should I say that Alastor fell in love with you... but what happens next?...All Rights Reserved
