—Hayate Todoroki!

Name: Hayate Todoroki
Species: Oni (son of Kishin, element of wind)
Birthday: December 14th
gender: male
Height: 1.76

Hayate speaks very loudly and is often told to calm down. As a child, his parents were killed, so the village doctor took him in. When the doctor was treating a Momo child, he said he was proud of him, considering him a grandfather, but he was killed by the same Momo child he had saved. From that day on, Hayate swore to kill every Momotaro until they were all exterminated.

— Hayate is euphoric, when he speaks he shouts and tends to interrupt what the other person has to say, drowning out the voices with questions he asks one after the other, until you despair.
— He has a terrible sense of direction; he often gets lost very easily.
— When he is at high altitudes or gets very dizzy, his cheeks puff out; sudden movements and heights often make him nauseous.
— He respects other people's opinions, he doesn't try to change someone else's ideals, he doesn't argue or try to make you think like him, he is understanding, brief and precise.
— He cares about his companions and the oni; he has a good heart.

Todoroki has blond hair, long eyelashes the same color as his hair, and yellow eyes. A small silver chain hangs between his lip and earlobe piercings, and he wears the standard Kikoku Unit uniform, which includes a cap and cape.

He doesn't always wear the uniform!
In casual situations he usually wears a black shirt, an unbuttoned striped sweater and a white cap.

What are the Children of Kishin?
There are 8 special Oni (Kishin no Ko / 鬼神の子) who strongly inherit the blood of Kishin , the most powerful ancestral Oni in history. They are born when the Oni population is near extinction due to hunting by the Momotaro. Each one controls a different element (fire, wind, water, earth, ice, lightning, light, and darkness) and possesses berserker-level strength and regeneration, far superior to a normal Oni. What is the conflict between Momotaros and Oni? It is an ancient, centuries-old war that inverts the Japanese legend of Momotarō. - Oni : descendants of Kishin. They live in hiding and manipulate their own blood as a weapon. The Oni Corporation and Rasetsu Academy organize and protect them. - Momotaro (Momotaro Agency): a paramilitary organization of the Japanese government created to exterminate all Oni. They use "black bacteria" as a power. For them, there are no good Oni: all are targets.

Long ago, the Oni lived isolated because of their own ferocity. Momotaro invaded them, and ever since, the two groups have fought in secret. The story is told from the Oni's perspective, portraying the Momotaro as discriminatory persecutors backed by the state.

Blood Eclipse Release: Like other Oni, Hayate is able to control and manipulate his blood through Blood Eclipse Release, creating unique devices based on personal experiences and/or interests.

Son of the Kishin: As a Son of the Kishin, Hayate possesses elemental power that transcends his Oni physiology. His elemental element is wind. He is able to control gusts of wind and manipulate their speed and direction.

Blood Sword Fugetsu: Hayate creates a blood sword that allows him to control the wind.
True Wind: Hayate unleashes many tornadoes against the enemy.
Fugetsu Sword Flash: Hayate attacks the enemy with his blood sword.
Berserk State: Hayate entered a Berserk state when Hizumi showed him his grandfather's hunched body. In this state, he controls powerful tornadoes.
