The firstborn son. A mood-maker who keeps the atmosphere lively. Because he was an unwanted child and born prematurely, he was beaten to death with an iron pipe the moment he was born. He helps the 6th child and the others meet Mama.

The second child. Calm and tsundere. She protects the younger ones as an older sister should. She doted on the 3rd sister. Immediately after birth, she was hacked to pieces with scissors by Mama. She helps the 6th child and the others meet Mama.

Gender unknown. Has neither testicles nor breasts. Always smiling and very kind. The 3rd child's body was taken by the Forceps and was melting away, so they entrusted their brain to the 6th child. Afterward, their soul merged with Seed-san to help the others meet Mama. The 3rd child was conceived with a sadistic client at Mama's workplace who had an abortion fetish. Since the pregnancy was intended for abortion in exchange for a large sum of money, there was no love from Mama, who even told them, "Never come (be born) to me again." They help the 6th child and the others meet Mama.

Attacks in order to cut you to pieces. Taciturn.

The twin younger brother of the 5th child. He wants to see Mama (the reason is not stated). He had no brain at first, but received the 3rd child's brain. He has no arms.
