A royal prince. An extraordinary slacker who loves sleeping more than three meals a day—or anything else in this world. His motivation for work is highly inconsistent; when he's not feeling it, nothing can make him move. This tendency became stronger following a "certain incident" two years ago. Despite his angelically beautiful face, he spits merciless venom whenever something displeases him. He was born somewhat lacking in a conventional "sense of morality" and hates the "ignorant masses" even more than he hates criminals. He enjoys oil painting, and the few pieces he painted years ago as a masked artist still fetch high prices today. He dislikes socializing because it's "a hassle." He dislikes mirrors because they are "too honest."

Madoka's butler. Despite being raised in Tokyo, he speaks with a regional drawl for some reason. He has a sturdy build and a loud natural voice. On the other hand, he has a refreshing smile and a soft aura, which made him overwhelmingly popular with children back when he worked at a flower shop. He is skilled with his hands and handles all household chores perfectly. His trademark is the apron he always wears, simply because he finds worrying about stains to be a bother. Since Madoka has been a chronic slacker since childhood, Seiichi has managed to keep him living a somewhat normal life by scolding, praising, soothing, and ultimately scolding him again. Perhaps because he views himself as a guardian, Seiichi is extremely indifferent to Madoka's beauty and will ruthlessly pull on his cheeks when he doesn't listen. "Seiichi Fumawake is the only person in this world capable of such violence," Kenzo remarks with indignation. He is arguably the sole reason Madoka remains on this side of the world.

Madoka's butler. He is soft on Madoka and forgives him for almost anything. On the other hand, he is jealous of Seiichi—the recorder and childhood friend whom Madoka holds sacred. He speaks to Seiichi with harsh, merciless words, often requiring Madoka to step in and mediate. He is quite multi-talented: he has been featured in sauna magazines as a Sauna & Spa Professional, holds certifications as a Tea Specialist and Tea Meister, and even has a column in "Weekly Tea." He can also cook things like cakes (though he's often overshadowed by Seiichi). While not quite on the level of Madoka or Jin, he possesses high insight and observational skills, earning him the praise of "extremely excellent" from the legendary recorder Sui Tou. Perhaps because he lost his family early, he struggles with being honest and relying on others. He sometimes overworks himself, only to be scolded by Madoka and forced to rest. He proudly declares himself a Madoka-lover and is a self-acknowledged "Slacker-Making Machine" (a title bestowed by Seiichi). In a sense, he and the lazy Madoka might be considered to have a mutually devoted relationship, or so it seems.
