She is one of Kei's close friends who also pursues a romantic relationship with Kei, but towards the end of the series discovers her affection for one of her teachers, Yamada. This inappropriate relationship is only ever hinted at, but it's more than obvious that something is going on between them when Yamada is confronted by the principal about him seeing Yamada and a girl from their school walking together. Her parents own a grocery store and she often has to go to deliver food that people ordered. Koishi has a happy-disposition to her personality and is only ever seen crying when it comes to matters that involve Kei. One of the things Ichigo would get irritated at was that Koishi would never act on her urges and in effect she waits too long, and by the time she does tell Kei her true feelings, he's already hopelessly in love with Mizuho.

In the OVA it is strongly hinted that she has begun a sexual relationship with her teacher, Yamada. During the scene where Mizuho's mother, Hatsuho, teleports herself and Kei to the front of a hotel, they are seen from afar by Koishi and Ichigo as they go in. Koishi acts surprised but Ichigo calmly replies that it doesn't surprise her to see two people be intimate whether in a hotel or in the room of the boy. This answer confuses Koishi who after a few seconds asks Ichigo if she is directing the comment to her. When Ichigo confirms this, there is a scene that flashes in silouhette which appear to be Koishi and Yamada during sex and Koishi angrily responds to Ichigo about how could she possibly have known about that. (During the entire series Ichigo had always been stalking her friends to make sure of their happiness).

It is also worth noting that during this scene, Koishi was neither upset nor jealous at seeing Kei walk into a hotel with another woman, she only showed herself upset at Ichigo knowing about her sexual relationship with her teacher, Yamada.
