Touma Kikuna

Kanako's mother. After her husband's death, she has been taking care of the house as the head of the family.
When her daughter gets pregnant, she tries to break them up for a while, but Kanako's stubbornness and Hiroki's sincerity make her approve (or rather order) their marriage and allows them to live together as a couple.

At first glance, she appears intelligent and arrogant, but in reality, she is still a sheltered woman, not so different from Kanako, and her strong desire to "protect the house and her daughter" leads her to believe that she must take care of Hiroki's desires.
