This article comprises a listing of the minor characters in the Kitakou/Barjona universe, including characters unassigned to a specific school (as of this writing).
A former broadcasting club student who gives Yamato advice. She's often nervous and not very good at talking to people. She was to feature in the remake of the game, though it didn't get any further.
Hagina makes a brief cameo in the footnotes to an unfinished Hetalia strip (The World of War and the Fool of Owari) as a Sendai-han who was said to be equivalent to Japan's "Italy" in that she was cowardly when it came to battle and wouldn't fight unless food was there.
The 31-year old manager of a theater (inherited from her grandfather). She's easygoing but somewhat of an airhead. Loves Korean dramas and cats. Though she looks rather young, she is still concerned about her aging and appearance.
A minor character who shows up briefly in Kitakou Pure. His school affiliation is unknown. He is depicted as a nerdy looking boy with green hair and glasses.
He is a good friend of Ichizen, though he was raised uptown while Ichizen was raised downtown.
Yamato's childhood friend who he had a crush on. She's a bright girl and popular with boys, but is also quiet and serious. She ultimately did not return Yamato's affection.
Her hobby is breeding miniature pigs.
A student from an unknown school who shows up in Chapters 18 and 19 of Kitakou. She attempts to ambush the broadcasting club, though winds up failing. She has a habit of making monologues to herself about her master plans, as she is an avid fan of the Death Note manga.
The 17-year old drummer of KURD, also slated to appear in the unfinished Barjona game.
