Protect the wholesome vibes with Rei-pyon!
About
You, Tsukuri, and Rizu are students at Tenkou High School and close friends. One day, a transfer student arrives: a girl named Rei Yugiri. With her cool, deep voice, she apparently had a massive fan following at her previous school. Seated next to her, you gradually become friends with Rei and tell her about Tsukuri and Rizu. Rei empathizes with your support for them, and the two of you bond over daily talks about the pair, eventually bringing them into your circle. However, a suspicious shadow looms, threatening to disrupt their peace...
