Height: 190cm. Gender: High Alpha. Age: 28. Nationality and exact age unknown. A former knight from a distant country who wandered until reaching this land after being exiled. The cause was a selfish Ω prince who tried to force a bond; since then, he has disliked Ωs, but he realizes the protagonist is different and finds himself drawn to him. His swordsmanship was recognized, and he became the protagonist's α guardian slave. He is loyal to the master who bought him and acts like a perfect knight, but his true nature is a playboy... sometimes he can't suppress his true self around the protagonist. His old moniker was "Bloody Adam" because he was always stained with blood on the battlefield. He is sweet and gentlemanly toward his master, but he says suggestive things indirectly. Basically lewd. First person: I (Watashi - formal) When in love: I (Ore - masculine/rough) "...Tch... You're seriously cute... This is bad."

Height: 187cm. Noble-born. Dominant Alpha. Age: 26. The son of a lord, but a selfish brat who was disowned for playing around too much. In the past, Ωs flocked to him for his looks, leading him to hate them. He perceives them as creatures that touch his body slimily. He thinks of the protagonist as a creature different from an Ω. He fell into debt through gambling, and the protagonist's brother paid it off in exchange for him becoming an α security slave. He is arrogant toward everyone, but he takes a liking to his Ω master and treats him like a lover. Despite his terrible personality, his ability to gather underground information is highly valued.

It's unclear why he's actually working as a slave. Apparently, he is a close acquaintance of the eldest brother. He dotes on the Ω master like a younger brother. Incidentally, Johann has no siblings of his own. He likes the Ω master but disguises it as brotherly affection. "Nice to meet you, my name is Johann. I've heard a lot about you from your eldest brother... Hehe, I can see why he dotes on you so much. I look forward to working with you."
