Mem-Cho

"So I presented myself as a high school girl, haha. My subscriber count went up tremendously! And by then I was in too deep to stop!"

Mem-Cho (ちょ) is a character in Oshi no Ko manga series. She is a Youtuber and a former Tik-Toker who participated in the reality dating show "My Love with a Star Begins Now" or "LoveNow". She was a girl who strived to become an idol at a young age, but due to her family situation, made sacrifices that ultimately ended with her becoming too old to become one. After LoveNow ended she was introduced to the revived B-Komachi group by Aquamarine Hoshino, one of its participants. Now, she works as an influencer for the group and one of its three current members.

Appearance
Mem-Cho is described as being attractive, cute, and innocent. She has aqua-colored eyes, brown hair dyed blonde, a cat smile, and small devil horns. Despite being twenty-five, she looks young.

Personality
Given her appearance, one can make sense that she is rather playful and mischievous. She engages in talks among youth talks to, as Aqua states, lie as a tool to protect themselves. She lied about her age, allowing her to save face and engage in jobs unbefitting her age. Despite this, she genuinely cares about the people she works with. Even before her hijinks, when she strived to become an idol, she was fine with setting aside her dreams to support her family, giving her a  strong sense of character.

Story
Ever since she was young, Mem-Cho wanted to become an idol, but her mother was single while managing three kids. She thought that finishing high school and getting a job straight away would be the best course of action to ease her mother's burdens. However, her mother didn't agree and wanted her to follow her dreams, so a young Mem-Cho applied for auditions to perform for a major label. This was cut short when her mother overworked herself and Mem-Cho's brothers needed to go to college, so she cut out of the auditions and started earning money through part-time jobs. She succeeded but ended up becoming too old to chase her dreams.

In this, she threw herself into streaming and lied about her age, which gained her many followers. Her Tik-Tok had no monetization, leading her to Youtube. After LoveNow had finished airing, she was invited by Aqua to join the new B-Komachi group. Although hesitant to join because of her age, she was received with welcome arms. Now, she works as both an idol and an influencer.
