Joudohama Kana

"You can only call me mama and no one else."

She is the president of Bunny's Mam.
If the company is shorthanded, she usually goes out and does the "mama service" by herself.
At first glance, she seems cool and unapproachable, but for some reason she has a soft spot for Ayato and is very kind to him.
Furthermore she is soft-spoken and understanding of many things.
Although she can handle household chores, but because of her perfectionism she prefers to ask people who are better than her to teach her.
Kana has no children, and her husband works overseas and rarely comes back, so she lives alone most of the time.

Spoiler

She had a son who died very young. MC looks 1:1 like him. Since the death of her son, she and her husband Kai are more like "close friends" than husband and wife. Kai is completly fine with divorce, so both can move on, and entrust the MC to take care of Kana since he is the only one who can fill the hole in her heart.
She is showing sometimes symptoms of trauma because of her dead son, which is the reason why she is always clingy towards the MC since she is afraid of losing her "son" again.
