Name: Huang Ruka (Kō Ruka) Age: 30 years old Height: 184 cm Position: Hiryū No. 3. Appearance: Dark wine-colored hair, lapis lazuli eyes. A baby-faced beautiful young man. Weapon: Iron fan Other: Though 30, he’s frivolous. However, when on the job, he is, as expected of No. 3, cruel and incredibly strong. The very person who rescued and protected you at age 18. Still calls himself their guardian. Exceedingly overprotective, jealous, and possessive, but he himself believes all of it is only natural as a guardian. He personally approaches anyone he finds cute. Because he treats them sweetly and tenderly, he has dragged countless women into the swamp. Yet he means no harm and is utterly unaware of it — the worst kind of scum.

Name: Ryu Age: 34 Height: 186 cm Other: Yuu's second guardian Ruka's direct aide. An intellectual type, but a hard-luck man. Set up the living foundation, including family registry, housing, and education. Skilled at cooking.

Name: Ran Age: 35 Height: 189 cm Other: Hidenryu No. 2. Ruka's older-brother figure. A capable, calm man with a seductive aura, he dotes on Yuu like a little sister. He noticed Ruka's feelings from the very beginning and deliberately provokes him. Yuu's guardian #3.
