Fully aware of the tall order ahead of him, the crown prince must brave these hardships in order to vanquish the foxes once and for all. He vows to fight until the bitter end, even if he falls in the process. Will justice prevail? Or will the royal family's second Demon Lord make the same mistakes as his predecessor?
