The Kitakou universe is home to not only the title school's broadcasting club, but also three other schools and their students. Most if not all of these characters' names are puns off of the various prefectures of Japan.
Due to Himaruya having indefinitely postponed the series, some characters are only given backstory or further details in profiles and otherwise don't figure very heavily.
The protagonist of the series. Noto is an idealistic young man who has long dreamed of attending Kitakou, due to great things he's heard about its broadcasting club. Little does he know that his life's just about to take a series of very strange turns.
Having started out as an average unlucky and meek type of boy, Noto's characterization abruptly headed off in a much different direction after the series Barjona Bombers began. After snapping and attempting to get his revenge on the Barjona cast, he's since taken on a more narcissistic and arrogant demeanor and adopted the guise of "Noto-sama".
