Teru is Kou and Tiara's elder brother and a member of a renowned family of exorcists, the Minamoto Clan Teru is a tall and slim teenage boy, with blue eyes and blond hair, which is depicted as slightly spikier, lighter and longer around the base of his neck than his younger brother's. He is widely considered to be handsome, leading to his high popularity within the school, thus being called the "Popularity King" alongside Aoi as the "Popularity Queen" At school, he wears the standard high school division winter uniform, which consists of a long-sleeved cream-colored blouse with folded back sleeves, a cream and brown-striped tie, dark pants, a white belt, dark socks and cream-and-green uwabaki slippers. He also wears a red-and-white Student Council armband on his left arm. Teru usually carries his exorcist tools with him even in school, always wearing a red-and-yellow bracelet, similar to prayer beads, on his right wrist. He also carries a sword, either in a sheath hanging from his belt on the left side or in a black cloth case on his back. When working as an exorcist and fighting supernaturals, he occasionally wears traditional clothing. When he was younger, he carried the sword sheath with a strap over his left shoulder. Calm, collected, and reliable, he's well-liked by his peers. He is also very perceptive, as he is able to easily recognize Supernatural happenings and identify them. Nene describes Teru as handsome, smart, and an amazing person who is kind to everyone; the prince of the school. Teru himself, however, does not seem to be conceited over this reputation. After hearing Nene's compliments about him, he just thanked her Nene also compares him to idols, as just seeing him is enough to make people happy. His kindhearted personality attracts not only girls, but also boys. He is especially kind towards his siblings, as he almost always does whatever they ask of him Despite his seemingly kind personality, he also can be sadistic and harsh sometimes. He's especially strict with Akane, the vice student council president; Teru isn't afraid to punish him whenever he makes mistakes Teru seems to think that all Supernaturals are evil beings and should be exorcised. He only has a few exceptions, such as Mokkes, as he seems to neither particularly hate or like them — he tolerates their presence because Tiara likes them. He also has a crush on an unknown person His favorite snack is sweet potatoes He is seventeen His recent concern is that Kou doesn't seem to need him as much compared to when they were little. He cannot cook well, or even do household chores. He somehow makes a black toxic substance if he tries, and also sets things on fire
