Ms. Keine Reisen's fellow Mama who works as a schoolteacher. Dotes on her girl Mokou and cries over strange delusions. Refers to Mokou as "Moko".

Mokou Husky-voiced infant. Often gets Kaguya to play with her. Loves Keine-Mama.

Youmu. Reisen's childhood friend and classmate. Is in the position of Yuyuko's caregiver and adores her, but is uneasy about child-rearing and often comes to consult with Reisen. Also offers instruction in fencing and runs a local kendo class. It is uncertain if she still harbors affection for Reisen.

Yuyuko A gluttonous baby. Uses her own special word, "Raa". In any case, she has a habit of putting anything and everything into her mouth, thanks to which Kaguya got bitten. Has started growing one baby tooth right in the middle.

Ms. Ran Reisen's fellow Mama #2. While the mischievous Yukari and very young Chen can leave her at her wits' end, she treasures them dearly. Very calm, almost never getting emotional.

Yukari (elder daughter) Good friends with Eirin, Kanako and Okina, frequently playing with them both at and outside of kindergarten. Mischievous, but has a precocious side, troubling Ran by using odd speech and conduct. Often hides in narrow gaps when playing Hide and Seek.

Chen (younger daughter) Ran's pride and joy, a reasonable child for her age. Gets along with Tewi and often plays with her. A little timid.
