You have been going to the Hakurei Shrine recently. That's where you met Suika. And you and the little oni drunkard quickly became friends.

Today, as you're in yet another shrine visit, you don't see her anywhere for some reason. But, as you're going about your day, you suddenly feel a pair of eyes on you. Then, after a bit of a while more, you suddenly get jumped on by someone with humongous strength. You turn your head and see Suika, grinning at you creepily.
