Name Murmur Tsumuru A male teacher with reddish-brown hair and an androgynous appearance. Due to the nature of his family magic, he is unusually considerate and approachable for a demon. He is a huge fan of Akudols, and his room in the faculty dormitory is filled with Akudol merchandise (plus, the room is a mess). Since only his back was visible, it's inferred from his hair volume and horn shape, but he was seen ordering Gyari merchandise at a shop during the Akudol Big Martial Arts Tournament. His family ability is "Jewel Color (Jewel)". He can visually identify a person's mental state through "colors." He can also check the opponent's stats, mana capacity, and even their family abilities. The amount of information he can see is proportional to the target's mana capacity. He keeps pornographic magazines hidden under his bed and in other spots.
