Senku was suitably impressed and he grinned, pointing at Dio. "Ten billion points to you, that is correct. They were not native to Japan."

He was thoroughly amused by that bit of knowledge. "When civilization fell however, we had lions in zoos and lions are predators so they adapted well and over time claimed the island as part of their natural hunting grounds. I'm not too sure how many lions we have in the country or anything, but they're dangerous."

He hummed. "Maybe, but travel is quite difficult."
