Reisei

Reisei ( 冷泉 ; forename unknown) is an offscreen character in Shiny Days.

Personality
According to Makoto Itou, Reisei appears to be the jealous type as Ikeda had warned him not to introduce him to any other girls.

Background
Reisei went to the same middle school as Ikeda and Makoto. As of Shiny Days, she is dating the former.

According to Otome Katou, Reisei, along with Ai Yamagata, had a crush on Makoto. However, given how Otome then claims that Ai eventually dumped Makoto, when in reality Otome sabotaged Ai's love confession, this claim is questionable.

Etymology

 * Her surname may originate from the Reizei family.
