Personality
Yumeri is sweet and polite, best described as a demure everygirl. She works hard on her singing and dancing ability which many consider her the best dancer of ChamJam. She gets easily embarrassed whenever Maki teases her. However, despite her talents, she worries about the rankings as she would much rather be in the back row to watch Maki from behind. She can be very anxious and worried when people talk about her and Maki tries to come up with explanations to cover up their close relationship.

Biography
She was one of the earliest members to join Chamjam along with Maki and Reo. When ChamJam debuted she was initially in the back row.

Yumeri secretly attended the Girls Festa to watch and support Maki. After the show, Maki tells Yumeri that she spotted her in the crowd and they both promise to be in the Girls Festa together for next year.

As the popularity ranking approaches Yumeri worries about not just her ranking but Maki's as well, as she wishes for Maki to remain in the top 3 and the threat of not being able to fulfill the promise made to attend the Girls Festa together. During the sports festival, Yumeri makes a deal with Maki that the loser has to do whatever the winner says, motivating Yumeri.

Suddenly Yumeri's rank increased to 3rd place and during one of the Chamjam shows was given the opportunity to perform in the front row. However, during the handshake meet, Sorane noticed that the length of the line wasn't as long as it should be for the rank Yumeri achieved. After the show, Yumeri is basked in the post-show adrenaline of being in the front row while walking with Maki. Yumeri tells Maki she'd much rather remain in the back row to watch from behind. This surprises Maki, causing her to drop her bag causing a huge number of Yumeri's CDs to fall out which Yumeri saw. Turned out that Maki had been buying Yumeri's CDs and voting for her to show the fans Yumeri's amazing dancing.

While Maki is talking with Sorane about her dating rumors, Maki says she isn't doing anything she would be ashamed to be seen doing, which is directed towards Yumeri which causes Yumeri to blush in embarrassment.

With the voting for the popularity ranking ending and results revealed, Yumeri has earned the 4th place spot and is also happy about Maki retaining a place in the front row.

During Christmas, Yumeri spends the night together with Maki. For New Years she spends it together with Maki. They go out together and are spotted and joined by Maina and Yuuka. Yuuka makes note of how close Yumeri and Maki are, which causes Yumeri to panic and attempt to play it off.

Maki catches a cold and Yumeri visits to check up on her. With both Maki and Yuuka being ill, Yumeri is nervous that she has to fill in and perform in the front row for the next performance. Maki attempts to encourage Yumeri, by giving Yumeri her cold.

Yumeri remembers her promise to Maki during the sports festival. Maki tells Yumeri that she wants her to try and surpass her, which Yumeri says she can't do. So Maki says to Yumeri to try and stand beside her.
