The following is a list of characters from the series C3 novel series, also known as C Cube (シーキューブ, Shīkyūbu).
The characters from C3 have received various reviews. In a first impression review, Chris Walden from Japanator stated that he thought that Haruaki has the personality of a "wet flannel". In conclusion though he stated that with the exception of Haruaki, and Konoha the characters were pretty "well fleshed out and interesting". Walden cited a lack of explanation of Konoha's cursed past, and Haruaki's boringness as issues, but praised Kirika's character for being well explained.[6][7] Andy Hanley from UK Anime gave a different take saying that the characters dip in, and out of plot advancement as the story suits without giving the viewer a chance to care about them too much.[8] In a review of episode five from the anime, Josh Tolentino from Japanator said it was strange that Kirika could obtain a personality in less than ten minutes while the series still had two "bland" main characters.[9]
