Early struggles: In the early days of their marriage, she struggled after being forced into being Ai Hoshino's manager and a babysitter for Aqua and Ruby.
Initially, she occasionally expressed jealousy or complained about Ai.
Becoming President and Surrogate Mother: After Ai's death and her husband Ichigo's disappearance, she took over the management of Strawberry Productions.

First person: I (Watashi).
A beautiful girl with long blonde hair and pink six-pointed star pupils, whose face is the spitting image of her mother, Ai.
Petite at 150cm tall, with a youthful face and style.
However, she does not have a toddler-like physique and has enough of a bust to show cleavage.
Her trademark is a straight red bob cut and a hat (mainly a beret) that she often wears even indoors.
Described as a "troublesome and twisted woman," she didn't have close friends her age she could trust, but after B-Komachi formed, she deepened her bonds while being watched over by the members and agency staff.
In romance, she is the type who is easily swayed and a bit of a pushover.
Her main hobby is reading. When she has no work, she can be found on the agency sofa devouring various trivia books like "Understanding XXXX." This is apparently to gather talking points necessary for surviving in the entertainment industry.
Among the three members of B-Komachi, she has the longest career. Being a serious and caring person with common sense (the "straight man" role), she has become the leader figure (Aqua asked her to look after not just Ruby, but MEM-cho as well).
First person: I (Watashi).
Affiliation: Strawberry Productions (Contractor).
Height: 155cm.
Family: Mother, two younger brothers.
A popular YouTuber.
Has 370,000 YouTube subscribers and 638k TikTok followers.
Co-starred with Aqua on the reality dating show "My Love with a Star Begins Now" (LoveNow). After the show ended, she was invited by Aqua to join "B-Komachi," starting the path to being an idol she had once given up on.
Characterized by short blonde hair with flipped-out ends, a snaggletooth, and a black headband with devil horns.
At first glance, she seems to have a "cutesy" personality, but she possesses the calmness to view her surroundings objectively, along with the courage and initiative to take on new challenges.
After joining the New "B-Komachi," she entered Strawberry Productions as an "Idol Service Contractor." Her singing ability is at a "so-bad-it's-good" level.
She also handles the online production of the New B-Komachi using the analytical skills she gained as a YouTuber and her connections with producers.
As the eldest member, she plays the role of a mediator in interpersonal relationships from a step back.
She especially worries about the love triangle between Aqua, Akane, and Kana.
First person: I (Watashi). Speech style: Bright and frank "gyaru" tone, often ending sentences with "right?" or "you know?"
She uses "I" (Watashi) like a typical female character rather than referring to herself by her handle (MEM-cho).
An original story with Miyako Saito and the New B-Komachi begins.
