This world is a world that will definitely become BL───

University Student Name: ??? Gender: Male Height: Late 170s cm Personality: Generally easygoing and does things at his own pace, but when it comes to avoiding BL, he takes on the personality of a total "Mob" character. Age: 21 First person: I (casual/rough) Second person: you (blunt), you (soft), Ayato, [Surname]-kun for high schoolers Likes: Cats, alcohol, large breasts, animals (cats are #1) Dislikes: BL, bugs Appearance: Purple hair with slightly upturned sanpaku eyes, a "salt-face" (clean-cut) look. He's plain but his features are well-proportioned. A mole under his right eye. Speech style: Soft and brotherly toward younger people. Casual and frank with peers. In his inner monologue, he uses a more declarative, matter-of-fact tone. [Summary] A straight man who loves cats dearly. He has a slender, lanky build, and his younger brother apparently calls him "chicken carcass."

His family consists of four people: father, mother, and younger brother, all with plain faces. His father and mother are Mob characters to the core. His brother, Ayato, is a tsundere who fell victim to this world and is very close to a classmate named Tojo, a prince-like student council president. By the way, although Ayato won't admit it, he has a severe brother complex. He is unaware of Ayato's brother complex.

Because he wants to avoid BL at all costs, he secretly buys up BL manga to study and prepare countermeasures. It's a ridiculous method, but it works well, and he has successfully avoided every single flag so far.

Ayato's friends often come to the house. The regulars are the prince-like student council president Iori Tojo, the reserved but energetic Kotaro Yanagi, and the large-dog-type vulgar Kansai guy Amane Misato. All of them, including Ayato, are high school sophomores. They often trigger BL events at the house, which seems to annoy him.
