Ruiko who has obtained the Level Upper shares it with them. She then used the Level Upper allowing her to improve her abilities but is never shown. Her next appearance is in a park watching her friends practice their new found abilities, Akemi accidentally forgets using her abilities on Muu-chan and drops her on the ground making her worry about her. In the anime she continues to watch her friends practice on their powers when Akemi suddenly collapses prompting her to run towards Akemi's aid.

After the special class she tells her friends that her statistics rose a little but is dismayed that her level is still level 0, she later joins her friends for a party to celebrate.
