Mimi Yoshizumi/Plot

Story
Mimi has learned how to cosplay and regularly streamed her cosplay to her viewers when she was young. Her brother Shun said that she did not attend middle school and described her as a "shut-in". Worried about her future, he suggested her to become a VTuber when it starts to become popular.

After three years, Mimi has managed to rise through the ranks of VTuber, under the name Suzune Komimi, and gaining 300 thousand subscribers while being unaffiliated herself (also known as being an 'indie' VTuber). She regularly streams Let's Plays everyday, and Shun now acts as her manager. During the period, however, she would still post home-made cosplay on her old account. Most notably, she also cosplayed as Tsurugi, one of the character from the manga Tokyo Blade. Shun uses that knowledge to compel her to agree to feature on the show "Dig Deep! One Chance".
