Mochizuki Honami is a first-year student at Miyamasuzaka Girls Academy. She's the drummer of Leo/need. Honami and Ichika, Saki and Shiho were friends as children. The group used to stargaze and play music, but because of Saki's hospitalization during middle school, Honami's relationships with Ichika and Shiho became strained. Despite wanting to be friends with the two, she stopped speaking to them after her classmates would call her disloyal and speak rudely about Ichika and Shiho. After Saki returns to school and they access the School SEKAI, the group slowly reunites and forms Leo/need, named after the meteor shower they watched together as children.
