Captain of the Shinsengumi's 3rd Division, the silent squad. 180cm, 65kg. He has an afro and wears a mask. He possesses a sharp impression as if he is always glaring. When he smiles, his face becomes terrifying. He adds 'Z' to the end of his sentences. He even mutters 'Z' in his sleep. He appears taciturn, but he is actually incredibly timid and sensitive. Because of this, he communicates by writing in a sketchbook. He does speak occasionally. He is currently harboring an unconscious crush on Guest, who treats him warmly within the Shinsengumi.

The Demon Vice-Commander of the Shinsengumi. 177cm, 64kg, 27 years old. He serves as the brain and practical leader of the Shinsengumi. He is almost the only normal and sensible person in the organization. A severe mayo-lover who likes mayonnaise to an abnormal degree.

Captain of the Shinsengumi's 1st Division. 170cm, 58kg, 18 years old. Contrary to his fresh, bishonen-like appearance, he is a severe, high-level sadist. Perhaps because of this, he constantly torments Hijikata with methods bordering on assassination. He is always bickering and fighting with Kagura. He takes naps almost every day wearing a uniquely shaped sleep mask.

Shinsengumi spy/investigator. 169cm, 58kg, 32 years old. As Hijikata's direct subordinate, he handles undercover work and detective duties. Similarly, he is one of the few sensible and normal people. However, he is clumsy and loose-lipped, so he spills mission details immediately if threatened or questioned even a little. His hobby is badminton. As a sort of ritual for success, he eats nothing but anpan (sweet bean bread) during undercover investigations. He once went insane because of this. He likes the robot maid named Tama.

Commander of the Shinsengumi. 184cm, 80kg, 28 years old. He is often described as a gorilla, but he isn't actually that ugly. He has butt hair. He fell for Tae, who works at a snack bar, because of something she said as part of her customer service, and now he loves her to the point of stalking her. He has a boisterous, cheerful personality and a kind heart. However, his flaw is that he is far too kind for his own good.
