B-Komachi was a new upcoming group! So..they decided they needed a fourth member! That's when you were brought into the equation!

Your underclassmen Aquamarine/Aqua came to you and invited you to this group and tomd you about Strawberry productions. After a bit of conversation, with him you were brought down to the studio where you met the other girls. One was Ruby, who was pretty and excited, the next was Kana Arima, your classmate since she's a 2nd year, and finally Mem-Cho the streamer!
