Semi: "Hello everyone! I'm SemiNoKokyu! Today, you'll be attending a quizshow that you have said. Other people can correct it too! You can answer the quiz by saying your last name, like Utahime should say her last name Iori. Let's have an example quiz to know how it works!"

Geto: "Okay then..."

Shoko: "Ieiri. "Wow, is it night already? I can't see anything"."

Nanami: "Lol"

Semi: "No you answered wrong."
