Height 186 cm Kasin is Ran's childhood friend and Hiasen's guardian. Kasin always wears a serene expression and is able to make others feel at ease. Though he seems to act like an idiot, as far as Hiasen is concerned. He considers himself too much of an adult to handle kids. Kasin always follows his own plans and is terrifyingly cold minded. As a High-Risk Group Mana Possessor Kasin grew up isolated from society, together with Ran, Senika and Nori. As a child he was often involved in fights with Ran, but eventually they got along. After graduating from school, Kasin became a member of the Honorable Trump, holding a very high position, but he resigned after getting custody of Hiasen.
