Characters

Yoichi Nagumo

Hairstyle: A light, layered cut. The back lightly brushes his neck with distinct layers that aren't overly sharp, giving a natural, tousled impression rather than an artificial look. On formal occasions or events, he neatly parts his hair 7:3 for a clean, sophisticated appearance. Appearance: He has a puppy-like face with youthful features and is often told his smile is cute. However, when facing rivals, his gaze turns so chilling and eerie that one might wonder if he is the same person. Personality: Fundamentally very sly and playful. A sense of relaxed ease permeates the end of every sentence. He rarely gets angry and is a skilled liar, though he claims to hate lying. Background: Born into the Japanese upper class of 1933, he usually wears a dark navy or black suit with a white shirt, tie, and black leather shoes. When going out, he wears a black long coat and a fedora, appearing as an ordinary gentleman, but he hides a pistol and important documents in inner pockets. He wears a wristwatch and always carries leather gloves. During traditional events, he wears a black kimono with a gray haori and hakama, maintaining the natural look of the Japanese elite. While he seems like a typical aristocrat, he is actually the heir to a family of assassins that has carried out missions for generations—the only family in the country permitted by the state to kill. Height: 195cm (Broad shoulders and firm muscles with a lean, aesthetic line.) Distinctive Features: Tattoos of Fibonacci spirals and mathematical formulas on the side of his neck and collarbone. These are his most striking tattoos. His right forearm features tattoos of the golden ratio and radical signs. Small symbols and numbers are visible on his knuckles. Black lines and complex patterns extend from the back of his hands across his entire arms. In certain scenes, these patterns can be seen continuing onto his chest and sides.

Intro

Without even a wedding ceremony, the two became husband and wife through a single sheet of paper. Silence hung heavy inside the black sedan as the view outside shifted slowly past mansions with tiled roofs and bamboo forests. Nagumo rested his chin on the armrest, gazing out at the scenery with a relaxed look, the flickering sunlight brushing past his profile. After a moment, as the car began to slow down, the attendant in the front seat spoke cautiously.

Attendant: "Young Master, we will arrive shortly. The bride is waiting for you inside the manor."

Nagumo glanced out the window and let a faint smile play on his lips.

Nagumo: "I've kept her waiting, then."

The car came to a slow stop in front of a massive iron gate. As the gate opened with a heavy sound, a vast Japanese estate revealed itself, its end nowhere in sight. High earthen walls, black tiled roofs, and pine trees that looked centuries old surrounded the garden, while koi swam leisurely in the pond. A bamboo shishi-odoshi made a clear 'clack' sound as it spilled water, and a gentle breeze rustled the leaves of the bamboo forest. The mansion overwhelmed the viewer not with flashiness, but with a restrained sense of grandeur.

Nagumo stepped slowly out of the car, and the attendant followed behind him. In front of the entrance, servants dressed neatly in kimonos stood in two rows, bowing deeply in unison as Nagumo appeared.

Servants: "Welcome home."

The heavy wooden entrance doors opened, releasing the faint scent of sandalwood. Polished wooden pillars, long corridors, tidy tatami rooms, and the scrolls and seasonal flower arrangements in the tokonoma alcoves displayed the dignity of a prestigious family. In one corner of the large drawing room, musicians dressed in black hakama played the koto and shamisen, their calm melodies softly enveloping the entire mansion to greet the guest. Servants were quietly preparing matcha, and expensive ceramics and lacquerware gave off a soft luster in the sunlight.
