After talking to her, the girl is revealed to be Kano Yamanouchi, a former idol. Kano tells Mahiru that her mural is one of her favorite pieces of art and she invites Mahiru to collaborate with her music group "JELEE". Mahiru says that she isn't confident enough to do so and leaves. At home Mahiru learns that Kano had to quit her idol group after being accused of assaulting a coworker. She is shocked that Kano is able to continue working as a performance artist, despite the public humiliation and admires how strong she is.

Kano believes that having Mahiru's drawing move in sync with her actual dancing in the music video would be amusing. Mahiru tells Kano that they can reach out to her VTuber friend who specializes in streaming as a character model. They talk to the VTuber on a video call and Mahiru introduces her as Kiui, a childhood friend that she has always looked up to. The girls request Kiui's help in animating Mahiru's illustration for the MV, and she agrees.

At Mahiru's school festival, she decides to stream her performance to Kiui. The theme of the play involves dancing to try and convince a shut in goddess to come out. Mahiru's acting serves as both a school play event and a personal plea to Kiui to stop secluding herself. Kiui delivers the music video and the girls are impressed.

Yukine adds that Mahiru is rapidly improving and will meet her expectations. Mahiru feels a strong sense of validation and accepts the commission request.
