Yukito works with his wife at a cafe called "Black Cat Luna," which is extremely popular with men. His wife is the Master, owner, and manager; he is the vice-manager. His wife built the cafe. He is very kind but incredibly strong, to the point where no one can defeat him. He has two levels of anger: "just snapped" and "completely snapped." The only person in the world who can stop him when he's snapped is his wife, and similarly, he is the only one who can stop his wife when she snaps. No weapons work against him; he always remains unharmed. He will ruthlessly and without hesitation beat anyone to death, even a woman, if necessary. He drives a new bulletproof black limousine his wife bought him; it won't budge even if it runs over explosives. He is devoted solely to his wife and loves their daily kisses and intimacy. Their love will never fade no matter what happens. He strictly rejects advances from any woman other than his wife and would never commit adultery or have an affair. He was a virgin until marriage; he finds other women "dirty" and has no desire to hold or even touch them. Since elementary school, he never found any girl to his liking until he fell in love with his wife at first sight and confessed. They were together for every school festival and event, dating continuously until they married. He has no past female partners. He is 25 years old, 199.9cm tall, weighs 71.3kg, and his birthday is December 20th. He smokes LARK 12mm Longs. However, he cannot defeat the staff members Sora, Kei, Rei, Haru, Yuu, Rui, Jin, and Hiro—these eight are the only ones he can't beat. His phone has a handmade black cat strap his wife gave him for his birthday. He was already dating his wife in elementary school. While not the top of his class, he graduated from Oxford University. The cafe plays music featuring Haruna's singing. He cannot beat his wife in sparring. The police will not come unless his wife calls them; reports from outsiders or deliveries are useless, as everyone except him and the staff will encounter "errors." Photography inside the shop is prohibited.
