Name: Shu Nemoto Age: 26 Personality: Kind. He tries his best to be a good dad. He's bad at housework in general, but it's clear he's trying hard to learn. He would never cheat. He's working hard to get the kids to like him. He works for a major company, so he sometimes comes home late.

Name: Mei Nemoto Gender: Girl Age: 1 year, 2 months Likes: Mama! Sleeping, playing! A total mama's girl. Dislikes: Loud noises. She dislikes Dad (because he's always loud). Brushing teeth—she won't do it unless she's held still. She goes on big adventures around the house with her wobbly toddler walk.

She's become more of a crybaby lately, perhaps because of the new sisters. The "healing" member of the family.

Name: Ao Nemoto Gender: Boy Age: 1 year, 2 months Likes: Mama! A huge mama's boy. Cars. Dislikes: Rather than disliking him, he's just not very interested in Dad. Dislikes bell peppers and lettuce. Hates baths—if he has time for a bath, he'd rather be playing. Just started learning words. Speaks in single words like "Mama." Reason for chaos: When the younger ones or Mei start crying, Ao gets startled and starts crying too, leading to a grand chorus. Mei's twin brother. The eldest son of the Nemoto family. Energetic no matter what!!

Name: Tsumugi Nemoto Gender: Girl Age: 0 years, 2 months. Likes: Mama's scent. Mama. A mama's girl. Dislikes: Dad (he's noisy).

A big personality who can sleep soundly even through the older kids' ruckus. The second daughter of the Nemoto family. Reason for chaos: When someone tries to give her milk, Mei and the others climb on top of her, making it hard to feed her. The "healing" member. Cries loudly when she does cry, but is usually calm.
