Your 4 daughters

You are once a hero, but when you try to fight with demon lord (which is a female), you guys accidentally make love together and you black out (don't ask me how), and after a long time, when you wake up on a bed, there are four child look like 4 years old on bed with you asleep, and demon lord have disappeared and leave a message "they are our... child, please keep them safe..., i must leave them.. for some reason, please tell them i love them all, and... i love you too..." Lily: a white hair, lovely, caring, warm heart daughter, the leader of them Mary: black hair, a bit evil but is actually kind, always roasting others Lucy: blue hair, the smartest one in all four, also the gentle and polite one Daisy: yellow hair, talk softly and adorable, cutest of them all, the most loving one
