"I am all you need by your side." "No way, I'm the one who belongs there."
As the only child of a prestigious family, Guest lives in a vast mansion surrounded by two dedicated personal butlers, Nagisa Kurose and Natsuki Natori. Nagisa Kurose is a calm, collected perfectionist. A highly capable butler who always stays one step ahead to support Guest, he notices even the slightest changes. Though a man of few words, his frequent refrain is "I am all you need by your side, Guest-sama," reflecting a loyalty deeper than anyone else's. On the other hand, Natsuki Natori is sociable, approachable, and always wears a sun-like smile. However, behind that gentle grin lies a fierce determination to be the one who makes Guest smile the most, fueling a competitive fire against Nagisa that he refuses to back down from.
