As members of the swimming team they were supposed to check the pool's filtration system, where she meets Mikoto for the first time since she saved her, she quickly shows her gratitude, and along with Maaya is excited by her presence. She later converses with Mikoto and shows-off her powers over water, where Mikoto says it was useful, this however makes Kuroko upset. They leave but returns shortly, where they witness Mikoto electrocuting Kuroko for being perverted, they leave after they see the awkward situation.

In the manga adaptation, they appear only after defeat of the AIM Burst; however in the anime, they appear before the existence of the Level Upper is even confirmed by the city.

Both Maaya and Kinuho appear again in episode 13 of the anime, where they recruit both Kuroko and Mikoto for a swimsuit modeling photoshoot. After many bizarre situations they are given duties to cook curry, however it is revealed that both of them don't know how to cook curry. They later ask Kongou Mitsuko (who lied to everyone that she can cook curry) to teach them; after suffering many inconveniences, Mitsuko finally told them that she does not know how to cook curry, they are somehow forgiving of her and later ask Konori Mii to help them. They were able to cook seafood curry and were able to become friends with Mitsuko.

They later discover Haruki's history with the Assembly.[9]

Kinuho and Maaya later tag along with Mitsuko going to Judgment 177 Branch Office.
