Trivia

 * Mikoto Suoh's actor and Reisi Munakata's actor appeared together as okama in K The Stage.
 * In K The Stage, one of Yata and Fushimi's fight scenes included Yata using his baseball bat to attack and using his skateboard to guard against Fushimi's sabre. Some of them were done while Ueda is carried by stagehands, to depict Yata's jumps with his skateboard. The skateboard doesn't fall off. It is revealed in the backstage that Ueda has two pairs of identical shoes. One of the pairs has the right shoe attached to the skateboard.
 * Keisuke Ueda introduced his character as "Yata Fushimi" in K The Stage. This caused an uproar among the cast and the audience, and he immediately reasoned out that there are a lot of people in the cast and staff that kept saying "Yata" and "Fushimi" so it can't be helped and was bound to happen.
 * In K The Stage, before Kaoru Marimura can speak, Arisa suddenly cried aloud, cutting out Marimura and surprising everyone. Marimura, right after saying her character's name, then cried in the middle of speaking.
 * Yoshihiko Aramaki revealed in K The Stage that the voice for Ichigen Miwa's haiku recordings are from Hayami Shou, Ichigen's seiyuu. He also said that he loves the "Ichigen-sama set" (the Kotowari and the recorder), to which Ryou Matsuda replied "Kimoi!", which is the running gag in the series.
 * The actor for Niki Fushimi in K The Stage -Lost Small World- was kept a secret (the official website has posted the actors and actresses in costume—along with their names—except for Niki, which only contained a "?" in it) until the day of the play itself, where it was revealed that Yoshihiko Aramaki will do the role, who also played Kuroh Yatogami in the same play and previous stage plays.
