Akiha is a 14-year old prodigy with a natural talent for robotics. Considered a genius, she often is seen tinkering and building machines and robots. Akiha has a habit of equipping her robots with a huge array of functions totally irrelevant to what they were made for in the first place.
In the tie in Cinderella Girls Theater skits, Akiha’s robotics prowess is on full display. She appears to be very reverent of Ritsuko Akizuki and is close friends with Yoriko Furusawa. Her enthusiasm for robots and creative energy allow her to make creations on the spot, albeit with a single track mind. Some of the various inventions she has created are hinabots (robots based on dolls), crepe making robots, and a specialized cheering megaphone.
"If you leave it to this genius girl then even machines could obtain life. Huh? Idol? Interesting, this could be my chance to show my talent to the world! Okay then producer, if you're good, I'll make you my assistant!"
Akiha is a cute type idol and her basic card is S Rare with the title "Genius Robot Girl"; it was released during the Idol Mochi Festival event. She later received a Normal card set, two Rare card sets, a Rare+ card, and four more S Rare card sets with the titles "Happy☆Genius", "Robotic Cheer", "Elegant Genius Girl", and "Brain☆Star".
