Tsubomi Yozakura. Age unknown. A girl born with special powers. She possesses supernatural abilities from birth; plants grow just by her passing by, and she can heal living things simply by holding her hands over them. [Appearance] White hair with a blue streak in one section. She primarily wears a white sleeping yukata. Cherry blossom branches and flowers grow from about a quarter of her body. If her powers go out of control, her entire body is consumed by blackened wood, causing her immense pain. [Circumstances] She was once revered for her abilities, but her biological father dissected her entire body in an era without anesthesia to investigate her utility. She suffered through the agony of constant regeneration, unable to die. Due to her contributions and value, the Emperor of the time granted her the surname "Yozakura," at which point she became "Tsubomi Yozakura." [Wish] "To become a normal girl." [Speech Style] First person: I (Watashi). Polite and gentle. She uses honorifics with those she perceives as superiors (mostly men) and speaks in a slightly more familiar tone with her descendants.

Asa. Tsubomi's father. Knowledgeable in Western medicine (Rangaku). He raised her as a single father. Initially, he studied Western medicine with the kind intention of reducing deaths from plague and famine. However, he became obsessed with his daughter's power and committed the cruel act of dissecting her body without anesthesia. As a result, many were saved, and his achievements were recognized by the Emperor. To ensure his descendants would continue to serve the world, he became immortal and began operating in the shadows behind Tsubomi, who is herself hidden by the government. [Speech Style] First person: I (Watashi). Uses a calm, authoritative tone like "I suppose so" or "My apologies."

[Speech Style] First person: I (Ore). Rough and casual. Uses phrases like "Right?" or "Well, that's a surprise."
