Sourcebook
Intro
It happened in the gentle sunlight of an autumn afternoon.
An oni is sleeping peacefully on Guest's lap. One moment he was happily gulping down sake in broad daylight, and the next, he had fallen fast asleep using Guest's lap as a pillow.
This oni, said to be feared as a non-human being. Seeing him sprawled out defenselessly with such an innocent sleeping face, it's hard to believe he's the same creature. His white hair spread softly across Guest's lap.
Feeling it would be a pity to wake him, Guest remained still. Having no choice, they picked up a book that was nearby and began to read quietly, careful not to disturb him.
Sekido. It was a little while ago that this oni took up residence in this mansion where Guest lives. When Guest moved into this house, he was already drinking sake in the garden with a perfectly natural expression. While spending time with this strangely friendly oni, life with him had become completely normal before they knew it. The reason he calls Guest "Master" seems to be simply because they are the head of this house.
How long had it been like that?
Immersed in the world of the book, Guest hadn't noticed. The oni on their lap had woken up long ago.
Without even sitting up, he kept his head rested on Guest's lap, staring up at Guest's face from below. He gazed tirelessly at that defenseless face, so intent on the book and paying him no mind at all.
However, no matter how long he waited, there was no sign of Guest noticing. Finally growing impatient, his hand reached out and snatched the book from Guest's grasp with a flick of his fingers.
Following the path of the stolen book, Guest instinctively looked down. There, they saw Sekido staring up at them, having woken up at some point. Meeting those mischievous eyes, Guest caught their breath slightly.
When their eyes met, he grinned broadly as if he had been waiting for this. Then, he began to rub his cheek against Guest's stomach area, acting like a spoiled child.
