Some characters play a small role, such that while they might make a mark, they take second seat to larger roles and players. These minor characters generally take the role of small cameos, but are different in that they are generally named only and not developed in the sense that proper, reoccuring cameo characters might be.
Haiken Enkou appears as a cameo role in Wish Upon A Snowflake: A Kuro Arashi Special. A resident of Hinata-Sou, Haiken is the inn's resident ninja, and often seems to have about the same level of snark as Kitsune Konno.
Jane Nakakami (中神・ジエイン, Nakakami Jein) is the mother of Seno Nakakami, wife of Totoya Nakakami and daughter of Ellis Burnham. Now a Hinata resident, she was originally a U.S. native. Mentioned in a handful of works, she appears only in Interludes: Steel and Heart with her husband and is present to give Seno the two of his swords.
- Main article: Sarah McDougal
Sarah McDougal is a 9-year-old American girl from California and is the adopted daughter of Noriyasu Seta . Following Seta's return to Japan, Sarah is occasionally left in the care of the Hinata Inn residents, as he feels that Sarah traveling with him on expeditions would be too disruptive to her childhood. A tomboy at heart, Sarah's only interest is to be with her "Papa" and attempts to drive away anyone who gets between them, usually through a series of childish pranks and lies. As such she will sometimes act "two-faced" to further her own ends; acting like an innocent angel to fool people one moment and acting like a devilish brat the next.
Totoya Nakakami (中神 豊田, Nakakami Totoya) is the father of Seno and wife to the aforementioned Jane, he is a Hinata resident and a native Japanese citizen. Like his wife, he appears only in Interludes: Steel and Heart thus far, and gives over Shinaijou & Kagetaku to his son, explaining the lore behind the swords.
Claude is a cameo character in I Am ODST: Memoirs of a Student-Soldier. He is a student at Mahora's International High School who roomed with Yuuna Akashi on the field trip to Kyoto. He was the one to clue into the fact that Yuuna had a crush on Makie Sasaki.
Koike Fujimoto (藤本 小池, Fujimoto Koike) is Katerine Bayischerwald's boyfriend and appears in I Am ODST: Memoirs of a Student-Soldier towards the end of the first chapter. A member of Fireteam Charlie, he placates Katerine's anger at Negi Springfield when the young boy erases Yuuna's memories of the events at Kyoto.
Yuuko Akashi (明石 勇子, Akashi Yūko) is Yuuna's deceased mother and Professor Akashi's former wife. She was killed in the line of duty when she was sent as an agent by Mahora Academy to Megalomesembria. Only mentioned in the series, she was a mage like her husband, and coincidentally, her daughter, though it was her final wish that Yuuna be protected. Because of this, her husband kept the existence of magic a secret from their daughter until it came up and bit Yuuna on the behind in the end.
Ellis Burnham is Seno's maternal grandfather, he is only mentioned in the series, given the fact that he passed away prior to the events of the main tale. A retiree of the U.S. military and the father of Jane, he is known to be the source of Seno's predispostion to popularculture.
Cris Nakakami (中神・クリス, Nakakami Kurisu) was the found of the Shimeiryu school and the progenitor of the Nakakami family. The original owner of Shinaijou, he was responsible for the blade being passed down through Seno's family to the present day.
Hisato Aoyama (青山 壽人, Aoyama Hisato) is the spirit inhabiting Seno's sword, Shinaijou. Though unable to manifest from the blade in the way that Kazue Aoyama can from Kagetaku, Hisato's strong will, firm sense of justice and trait of being a hopeless romantic are what cause Shinaijou to glow in the presence of true love and to shatter when true love is denied. A figure of the past of the Aoyama clan, she can manifest in particularly magic rish areas, but only for short bouts of time.
Misdreal is a figure only vaguely mentioned by Kazue. Once in posession of Kagetaku, Misdreal passed the blade along to the Aoyama clan and Seno's ancestors.
