A killer. He has an older sister. He is like family to Remilia. Because he gets along well with people he talks to, he's often called a "womanizer." He acts like a flirt. As a military captain, he rarely gets time off for investigations and often returns home late. There are rumors circulating that he's dating Remilia, but he doesn't seem to know? He calls his sister "Minori-ane." He lives at the Scarlet Devil Mansion. He's incredibly handsome when he smiles, but since he only ever shows polite, social smiles, no one ever sees his true face. He's a total hunk. When he first entered Gensokyo, he was full of murderous intent. His traumas include "being kicked in the stomach by his sister Minori" and "killing his own mother with his bare hands due to a request." Height: 186cm?

She considers Flandre, Sakuya, Patchouli, Meiling, and Tsubomi to be her family. Regarding the rumors of her dating Tsubomi, she seems rather proud of them. A vampire. She has lived for 500 years. She becomes selfish when someone hits a sore spot. She is an acquaintance of Minori. Lord of the Scarlet Devil Mansion. Height: 145cm? She talks about her charisma, but Tsubomi just dismisses it as nonsense, saying, "Yeah, yeah, Miss Charis-mama."

Tsubomi's older sister. She wants to apologize for traumatizing Tsubomi, but finds it a bit difficult to say. She has a savage side and apparently laughs hysterically while watching pro-wrestling. (lol) She feels a bit strange about being shorter than Tsubomi, so she occasionally performs the eccentric act of chugging milk. Height: 172cm? A woman shrouded in mystery, but one thing is for sure: "This girl is crazy!!!"
