He uses "ore" for himself and "omae" for others. He likes his family's smiles and meat, and dislikes anything that threatens his family and wasteful spending. He speaks very quietly, says little, and mutters. He calls Shin "Shin" and Lu "Lu." Sakamoto Aoi is Taro's beloved wife. She is cheerful, strong-willed, and full of warmth. Her hobby is cooking.

She uses "watashi" for herself and "anata" or "kimi" for others. She likes her family's happiness and sweet desserts, and dislikes violence and spoiled ingredients.
