Kiritani Haruka is a second- year student at Miyamasuzaka Girls Academy from HATSUNE MIKU: COLORFUL STAGE!. When she was at the mall an idol invited her to dance on stage this made Haruka want to become an idol because of how happy she was at that moment, and she would then become a part of the group called ASRUN where she would be ranked with the highest popularity. She would later then have a falling out with one of the other members in ASRUN and this causes her to retire from being an idol, but she would then meet Minori who would invite her to create MORE MORE JUMP with Minori, Airi, and Shizuku.
