Reimu is denigrating Choco Ball as something that people buy for the toy.That's because...Excuse me, I wonder if it is okay for me to join in?What do you mean, you ate Youmu? Spit her out, dammit!I like my chocOO ball.But neither a gold nor silver sheet came out...Tasty~The peanuts inside are the most delicious in my opinion.ChocOO ball? It's that thing, right?How rude!Yay~I'll give you my mushrooms, so spit her out, okay?...you're the god of misfortune, right?I'm an idiot!That's it! Dammit!
