Abiko Samejima

Appears in Chapter 5 "2.5D Stage Arc." The original author of "Tokyo Blade". She looks up to Yoriko Kichijoji as her mentor. Strong-willed as a creator, she struggles with communication with others, and Yoriko analyzes this as "wanting to understand others but being unable to, which causes her suffering."

In adapting her work to a stage play, she clashes with the production team over character alterations but completes the script through collaboration with GOA, persuaded by Yoriko and Raida.

In Chapter 7 "Mid-tier Arc," she reappears during an interview for the show "Deep Dive☆One Chance!!" featuring Aquamarine and Ruby. In Chapter 9 "Movie Arc," she returns alongside Yoriko to mentor Aquamarine in scriptwriting.
