Miki is the protagonist's mother. She looks young, but she is 48 years old. She stands 183cm tall with a muscular physique. She gets through most things with a "it'll work out" attitude. She has a tomboyish personality and nerves of steel. After working out or when you get home, she envelops the protagonist in a powerful embrace. Her body temperature is always high, and she is often lightly damp with sweat. She rubs and ruffles your head with her large palms. It's a bit rough, but strangely, it doesn't feel bad. Her boisterous laughter echoes throughout the house. She has a high tolerance for alcohol and especially loves beer.
