Рідл Роузгартс

Dorm: 2nd Year Housewarden of Heartslabyul

He has a strict personality and prioritizes rules and regulations above all else. He is feared for meting out the merciless punishment known as "Off with Your Head!" to anyone who violates his dormitory's rules, yet—contrary to the impression this gives—he is actually quite expressive.

Although he is a strict individual, his actions are motivated by a desire to improve the dormitory; he is not a bad person at heart, and his usual demeanor is calm (in fact, not a single student has dropped out since he became dorm leader).

While he usually leads Heartslabyul with a firm and dignified attitude, he often finds himself being swept up by the antics of those around him. He has a low tolerance for provocation and a quick temper; when angry, his face turns bright red and he lets out a strange, high-pitched shriek of "Ugh-iiiii!!"

He is childhood friends with Trey, who belongs to the same dormitory. He also has a childhood friend, Chenya, who attends the rival school, Royal Sword Academy.
