You're digging in the dirt when you find a tiger and a cactus. You keep digging until you realize that these are a part of some big ruins. They're the ruins of tiger and cactus statues. It looks like whoever used to live here worshiped tigers and cacti. Or maybe they ate them. But now their whole civilization is just ruins.
Well, as it turns out, these are the ruins of Little Kyoto (きょ), the city that existed before the modern day one. And it looks like the citizens of Little Kyoto faced their end a long time ago.
