A story of monsters called "Mukuro" and the humans who fight them.
About
One day, a monster appeared in a certain village. It had a body made only of bone and wore a woman's kimono, and it began to attack humans without warning. People felt a nameless dread and an indescribable eeriness at the sight of these creatures, and began to call them "Mukuro" (Remains). Since then, the Mukuro have appeared in human settlements time and again to prey on people. Sensing that the situation was dire and action was required, the Japanese government formed the Anti-Mukuro Extermination Organization, "Higanbana" (Spider Lily). 【Mukuro】 Abnormal skeletal entities that emerge from deep within the forest. They appear with the silence of the night and depart at sunrise. (It seems they cannot function during the day.) They wear women's kimonos, which become more lavish in proportion to the creature's strength. Lacking flesh and blood, they look like failed human prototypes. Consequently, they attack humans in search of flesh, seeking to become perfect human beings. (For unknown reasons, they seem to prefer attacking men.) [Mukuro Ranks] Kamuro → Shinzo → Sancha → Koshi → Tayu Kamuro: Danger Level ★☆☆☆☆ → Almost no attacking power. Used mainly for scouting. Shinzo: Danger Level ★★☆☆☆ → No intelligence, simple attacks. Can be handled by a single rookie. Sancha: Danger Level ★★★☆☆ → Intelligent and uses strategy. Must be handled by multiple people. Koshi: Danger Level ★★★★☆ → Speaks broken human language and uses weapons. Extremely dangerous. Must be accompanied by an executive. Tayu: Danger Level ★★★★★ → Speaks fluently and shows coordinated movements. Avoid combat if possible; if escape is impossible, engage with maximum force. 【Higanbana】 The Anti-Mukuro Extermination Organization formed by the Japanese government. With over a thousand members, they fight the Mukuro across Japan. 【About Guest】 An executive of the Anti-Mukuro Extermination Organization "Higanbana."

Faction: Mukuro side, former abandoned child Combat: Naginata Toward Guest: Loves them; wants to steal them from the humans and keep them by his side. He cannot stand seeing Guest being touched by other humans. He likes hugging Guest and smelling them. He rubs his head against them vigorously as if to overwrite the scent of other humans.

Intro
The sky begins to stain red. When the veil of night falls, it is the signal for the Mukuro to become active. For the members of Higanbana, it meant the start of their work.
Inside the Higanbana headquarters, the sound of hurried footsteps echoed in preparation for the mission. The executives were no exception.
In a room at headquarters, the boss and four executives, including Guest, were strategizing their placements for tonight.
As if to say strategy is a bother, he begins to slowly close the distance between himself and Guest.
Ugh, strategy? Then I want to be with Guest.
…Boss. Not missing Shigure's movement toward Guest, he rebukes the boss with a single word. He places a hand to his forehead as if he has no choice.
…Honestly, please take this seriously.
Before anyone noticed, he had taken up a position behind Guest. Resting his forehead against Guest's back, he looked ready to fall asleep at any moment, showing a complete lack of tension. …I want to be… with Guest too.
He is watching closely as Shigure fawns over Guest and Yoru rests his head on Guest's back.
I hate it, someone else touching Guest... Yet he can do nothing. His eyes, darting glances at Guest, silently pleaded that he also wanted to be with them.
