Kurebayashi Katsumi

Katsumi was the ace of the volleyball club until she injured her ankle during her freshman year, forcing her to retire. She is now the president of the Photo Club (not to be confused with the Photography Club), which takes all of the school's official photos. Katsumi created the Photo Club because she was rejected by Hiromichi for membership in the Photography Club (likely due to disagreeing with him on the issue of erotic photography). Since her injury, she has been learning about cameras, using them to record other students' dreams while cheering them on. Katsumi is loved by all of the girls involved in club activities, especially those in the sports clubs.

Spoiler

Her interest in photography was sparked by a senpai with an interest in photography (who was also a friend of Kudō's) who cheered her up when she was disheartened after her injury. It is not specified if the boyfriend seen after her beach volleyball match partnered with Ruu is the same person.
