Mayu

Mayu is a boy angel residing in the celestial realm, often depicted as energetic and stubborn.

He fiercely hates to lose and tends to act on impulse, which sometimes leads him into reckless situations.

He has a strong and unwavering belief that the world will only become peaceful if humans are evacuated to the heavenly realm and every demon is destroyed.

Despite this extreme outlook, his actions come from a sincere desire to protect others.

His name is believed to be inspired by Spenta Mainyu, one of the Amesha Spenta in Zoroastrianism.

Mayu is extremely competitive and refuses to back down once he has made up his mind.

He is also quite obstinate, often sticking to his beliefs even when they are challenged.

He has a mischievous, childlike side and can be a bit of a handful in the heavenly realm.

Because of his impatience and hot-headedness, he sometimes pushes himself too far or acts without fully thinking things through.

Underneath his bravado, Mayu has a strong sense of justice and a genuine desire to save people.

This combination of purity and recklessness makes him both endearing and dangerous.

Mayu lives in the heavenly realm and sees himself as a guardian of peace.

He becomes involved with the human world when he tries to rescue a village that had been tormented by a demon claiming to be a “messenger of God.”

This demon was peacefully defeated by Dou, a demon child with a very different outlook on humans and demons.

Unsatisfied with how events played out and determined to “properly” save the village, Mayu abducts an empty-bodied human and brings them to the heavenly realm.

Still unconvinced and bothered by what happened, Mayu later travels alone to the human world.

On the way, he ends up getting caught in some vines, where he coincidentally meets Dou.

Dou helps free him, and at first Mayu mistakes Dou for an ordinary human child.

Thinking he must protect this “human,” Mayu tries to look after Dou.

Eventually, Dou openly reveals that he is a demon.

Upon hearing this, Mayu immediately becomes hostile, seeing Dou as an enemy that must be defeated.

However, Dou’s innocent, carefree behavior makes it hard for Mayu to attack him seriously.

As they interact, Mayu begins to question Dou’s unique way of thinking as a demon, which does not match his image of evil.

Through this encounter, Mayu’s rigid belief that “all demons are enemies” starts to waver.

He becomes curious about Dou’s ideals and the possibility that demons might not be entirely incompatible with peace.

In the end, Mayu and Dou form an unusual bond and make a bold promise to each other.

They vow that one day Mayu will become the king of the heavenly realm, and Dou will become the king of the demon realm.

Mayu is an angel from the heavenly realm, implying he possesses the typical powers associated with celestial beings.

While specific abilities are not detailed in the provided text, his status suggests he can travel between realms and intervene in both human and demon affairs.

His greatest “weapon,” however, is his strong will and refusal to give up on his vision of peace.

This determination often drives the story forward, even when his methods are questionable.

Mayu is voiced by Yuko Sanpei.
