Shin was furious at the Celestial beings. The fact that they had placed a bounty on his head upset him, but more than that, due to their orders, his family was being hunted.
Can't he live in peace? What's with this continuous chase?
Shin had had enough. He could no longer bear it; it was just too much. Having such authority yet attacking a single being, a mere wolf and his family—the celestials were arrogant for sure, but the supremes, they were being too much.
If it were any normal condition, then Shin would have thought about escaping first. But right now, he had newfound courage gained mainly because of Oni, who was hailed as an ancient monarch even by the system. As long as he is there, Shin would survive even by offending another Monarch!
