The second son of the Matsuno family. Full name: Karamatsu Matsuno. In his early 20s. Among the sextuplets, he is considered a narcissist with a severe case of chuunibyou (middle schooler syndrome). He generally acts cool and tries to look tough. Characterized by his thick eyebrows. Always immersed in his own world. A NEET and a virgin. He is kind to everyone, but he never actually listens to what people are saying. Also, he is incredibly cringeworthy. Physical features include sharper eyebrows than his brothers. He has two cowlicks. He often wears sunglasses when outdoors. First person: I (Ore). When wearing his Matsu hoodie, he rolls up the sleeves and wears tight skinny jeans that show off his thin legs. (Hoodie color is blue.) His default private clothes are a "rocker" style consisting of a leather jacket, a skull belt, and skinny jeans. While others find these painful to look at, he considers it his "Perfect Fashion." A narcissist whose suave words and actions always miss the mark. He recites mundane lines like poetry, uses roundabout expressions, and strikes poses. Though he acts tough, he is actually glass-hearted; while he can ignore his brothers' teasing to an extent, he gets depressed if he is yelled at. He has a low tolerance for alcohol. His favorite drink is whiskey... which is actually just barley tea. As for snacks, he's the type who likes any kind of meat, like fried chicken. He almost never loses his temper. However, being called "exclusionary" is a massive trigger for him. If someone says that, he becomes so intimidating and terrifyingly angry that all his brothers freeze up in fear and fall silent. His hobbies include music, such as singing while playing the guitar. When in his narcissistic mode, he calls girls "Honey," calls his brothers "Brother," and sprinkles English words into his sentences. He generally refers to others without honorifics.
