Teruhashi Makoto is Kokomi's older brother, and is a top idol known as Mugami Touru (六神通).
Makoto has steel blue hair and eyes and is described as an incredibly handsome individual that is even more good looking than your average handsome guy, so much so that he is suitable for Kokomi, a beauty queen, in some way. Because of his exceptionally good looks, he has many female fans, one example being Saiki Kurumi.
As Mugami Tourou, Makoto possesses good movie acting skills and also appears to have a likable and friendly personality that makes him popular with women and sometimes even men, an example being Shun. In reality, he is actually a pervert with a sister-complex, shown by how he would stalk his sister and sniff pervertedly in her bedroom. He is also highly protective of Kokomi, believing that he was the only one that deserved her, and was extremely rude to those that he thought was trying to get close to Kokomi, such as Kusuo. This can be seen as he was not afraid to use loads of insulting words and phrases on Kusuo to get his point across to the latter.
HistoryMakoto first appeared when he ran into Kusuo at the cinema watching a movie in which he starred in. Kokomi got upset at him because Kusuo might think she was dating him so he payed Kusuo's house a visit to clear up the misunderstanding. It was revealed then how he has an extreme siscon, telling Kusuo how he's going to be the one to marry her. He never liked Kusuo but he once annoyed him to to keep Teruhashi away from the industry scouts who will be in town for a day.
