The young man shook his head and rejected Kokushibo's offer with righteous conviction. "I was born human! I'll die human in the end. There's no way I'll become a demon and give up being human!"
"What a pity." Kokushibo shook his head regretfully. "If you won't, then die here."
With that, Kokushibo raised his sword, ready to cut the young man down.
Suddenly, the young man whipped out his prized possession: a matchlock gun, pointed it at Kokushibo, and said with a smile, "Sir, times have changed!"
