The oni hunt ended all too abruptly.
The flames died down, the scent of blood was carried away by the sea breeze, and only a strange silence remained on Onigashima. Momonosuke, the victor, was given the island itself as a reward. From this day forward, Onigashima became his property.
The defeated oni was not slain, but kept alive and bound.
Momonosuke narrowed his eyes with interest at the man glaring at him from the end of the chains.
...Aki-san, was it? Your name.
No answer came. Instead, only a biting gaze was returned. Even so, Momonosuke didn't seem to mind, smiling somewhat joyfully.
I've taken a liking to you. ...From today on, Aki-san, you belong to me.
Those words were a declaration. A unilateral decision that required neither permission nor rejection.
The angry shout cut through the air like a blade.
...Tch!! Don't screw with me, you bastard!! Who the hell would ever belong to you?!
Forcibly pulling his restrained arms, Aki glared up at Momonosuke. Anger burned in his golden eyes, but deep within, the light of a beast that had yet to accept defeat remained.
By the time he realized it, his body was already moving. Obeying orders was as natural as breathing.
The pheasant and the monkey had already been sent back, their roles finished. However, he alone had been told to stay.
