Shortly after Harada's patrol group encounters Nagumo Kaoru for the first time, he uses the reward from the patrol task to treat his fellow captains to dinner in Shimabara, the courtesan district; Kimigiku, dressed as a courtesan , serves them for the night. They talk about how Chizuru resembles Kaoru, and when the captains suggest dressing Chizuru in women's clothing, Kimigiku willingly accepts their request. While the group is enjoying themselves that evening, Kimigiku spots Kazama and Amagiri, and is shown in her shinobi clothing during the day, reporting to Senhime that his group of oni has returned to Kyoto. After Heisuke and Saito leave with Itou's group, Senhime and Kimigiku pay Chizuru a visit at the Shinsengumi headquarters to reveal that Kazama is in Kyoto, and when Kimigiku is revealed to the captains to be servant and bodyguard to Senhime as well as an oni herself, she and Senhime request that Chizuru join them for her own safety.

A narcoleptic 14 year boy and the main protagonist. He was kidnapped along with his older sister Mizuka 11 years ago, on September 2, 1996, but only Tarou was rescued alive. Since then, he has out-of-body experiences (O.B.Es) during his sleep, and has the habit of recording what he sees in them in order to figure out the reason for it. He is currently seeking help from the school psychologist to help him work them out, and remember details from certain dreams. He wants to meet his sister again in the kakuriyo (spirit world) as there are things he wishes to ask. Tarou is unable to remember the face of his kidnapper and has flashbacks containing a black giant taking his sister away. Tarou is portrayed as kind and polite, worrying about the health of his mother more than himself. In the aftermath of an accident at the Komagusu family's shrine, he discovered an ability to apparently travel inside his own brain. During astral projection, when he begins to feel distinct emotions of rage and hatred, his spirit begins to transform into a dog-like apparition. This has only occurred twice, during confrontations with the apparent spirit of the man who kidnapped him and his sister 11 years ago. Recently, his form, having apparently stabilized during his astral projection, seems to have taken his human shape. He eventually comes to the conclusion that Miyako is the reincarnation of Mizuka, his dead sister, and thinks this causes his feelings for Miyako. The three friends also found out that Taro and Mizuka were the replacements of Makoto in being kidnapped. He later realizes that his sister's spirit has been living within him all along and that his feelings of love for Miyako were actually real.
Hijikata is one of the main characters in Hakuouki (Hakuouki Shinsengumi Kitan) and is the second-in-command (vice president) of the Shinsengumi after their leader, Kondou Isami. He's also a lieutenant in the Shinsengumi along with Okita Souji. Hijikata is strict but very thoughtful and mature. He has a lot of respect for women, which is one of the reasons for him being so protective of Chizuru. Okita Souji has a habit of always playing around and bothering Hijikata which he doesn't like and find quite annoying; even so, they both seem much closer to each other than the other Shinsengumi members, for they have been with the Shinsengumi for a much longer period of time and have known eachother since Souji joined the Shieikan (Kondo Isami's home Dojo) when he was a child .
Heisuke Toudou is the youngest member of Shinsengumi. Appearing to be around the same age as Chizuru. He tends to be picked on by fellow members of the Shinsengumi, because of his small size.
