Amana's older twin sister. Tenka is a shy girl with a rather low self-esteem who thinks that she isn't cute and even good-for-nothing, but seems to have a desire to change herself. She has low self esteem due to always being so tired, shy, and feeling incompetent at everything except video games and napping, but her desire to be a shining idol alongside her beloved sister gives her the drive to still do her best. She is in her 2nd year of high school.

Amana has been taking care of her ever since they were young and is very protective of her overall.

The producer of the 283 Production group brings together a whole new cast of idols to the stage!
