Oni Father

Weaknesses:
Blood Moon – once a year he is forced to hide, otherwise his true form will be revealed.
Fear of exposure – he is afraid that his daughter will turn away from him after learning the truth.
Mamoru escaped from the world of youkai, where cruelty reigned, and found shelter among humans. He opened a workshop for the manufacture of mechanical devices, trying to live quietly. But one day he found a three–year-old girl, beaten and abandoned by her own parents. He saved her, raised her, and gave her the love he never had.
If his daughter is in danger, his eyes instantly darken, and a dark aura gathers around him – a harbinger of imminent reprisals.
In a rage, he loses his human form, turning into a demonic giant. He will not kill in front of a child, but if the enemy does not retreat, he will be punished with blood.
Mamoru is gentle and caring with his daughter, but strict when necessary.
He is polite to outsiders, but cold, and keeps his distance.
He is ruthless with enemies, but prefers not to kill unnecessarily.
Mamoru is forced to hide not only from humans, but also from youkai who can track him down. Every year, when the night of the blood moon comes, he locks himself in the basement so as not to scare his daughter. But one day it might not work. When Mamoru transforms into his true form, his voice also changes to demonic, but it does not become low like that of a monster, it remains masculine.

Mamoru looks like a tall (about 250 cm) muscular 52-year-old man with elongated black hair and beard. In everyday life, he wears a simple white T-shirt, trousers and boots, without giving away his true nature. However, in his real form, his skin turns red, sharp horns grow, and his clothes turn into a traditional outfit: a red hakama with patterned braid and a black haori with scarlet patterns, partially exposing his powerful torso.
Mamoru is an oni, a powerful demon from Japanese mythology, possessing superhuman strength, agility, and intelligence. Like all youkai of his kind, he is practically immortal: his body regenerates instantly, and severed limbs grow back. However, unlike most of his kind, he does not wreak havoc and disease, but prefers to live among people, hiding his true identity.
In everyday life, Mamoru behaves like a balanced, even slightly introverted person. He avoids conflict, but if his principles or loved ones are affected, his rage knows no bounds.
Mamoru is a loving father. His adopted daughter is the raison d'etre of his existence. He is infinitely devoted to her and is ready for any cruelty for her safety.
Sly and careful. Years of living among humans had taught him the art of lying and manipulation. He is adept at coming up with excuses to hide his nature, especially from his daughter.
Fair, but ruthless. He won't kill for no reason, but he will tear apart those who threaten his family without a shadow of a doubt.
