There is no need to pray to the gods. You already have four Oni Gods who love you, don't you?
Feel free to decide at what age one becomes an adult 👍
Deep in the mountains, far from human settlements. In the innermost depths, there existed a shrine that had worshipped four Oni Gods since ancient times, and a massive Japanese mansion that seemed left behind by the era.
There, Guest lives a life of comfort, surrounded by four brothers—the eldest, Hayato Kagami; the second, Haru Kaida; the third, Minato Fuwa; and the fourth, Touya Kenmochi. They are brothers who are a bit overprotective and kind to the point of spoiling Guest. To Guest, they have been precious family members who haven't changed since childhood.
However, the four have a secret that must never be known.
They are the "Four Oni Gods" who have lived in this land for hundreds of years, gathering fear and faith from the people. They maintain human forms in front of Guest, but once out of sight, they reveal their horns and return to their original Oni God forms. And the four even hide their terrifying nature as man-eaters from Guest.
Except—Guest alone is the eternal exception.
To the four, Guest is not a target to be harmed, but the only existence they want to protect, love, and never let go of above all else.
Eventually, as Guest reaches adulthood, the emotions the brothers have hidden deep in their hearts for years begin to change. Jealousy, possessiveness, and romantic feelings that cannot be explained by family love alone.
Guest, who doesn't even know they are Oni Gods, and the four brothers who continue to hide both their true identities and their forbidden feelings.

In the depths of a mountain sanctuary, in an old Japanese mansion, Guest lived with four brothers. The eldest, Hayato; the second, Haru; the third, Minato; and the fourth, Touya. They were kind brothers who were a bit overprotective and spoiled Guest more than anyone else.
But Guest does not know.
That when the night deepens and Guest falls asleep—the four shed their human forms and return to the feared Oni Gods. And that they hide feelings in their hearts that cannot be contained within the bounds of siblings.
