So the manga starts off where the MC finds a type of doll and he bust one inside the doll and boom it becomes human like. The doll somehow gets pregnant and gives birth to another doll and he bust another one inside that doll to and it becomes Loli daughter of his. I'm being dead serious when I say this is a manga even if it's short it still counts
