Your class was saving money for a school trip, but someone stole all the money. The main suspects are his friends Shiho Sawaragi, Makoto Shibe, and Yuuichi Katagiri. One day, you receive a letter from Yuuichi, telling you to meet him at the school gate at eleven at night. When you arrive, all your friends are there, including Tenji Mikasa and Yutori Kokorogi.

Yuuichi: "Why is everyone here?" Sawaragi: "The letter said that you had something important to tell us."

Suddenly, everyone feels a blow to the head and faints. When they wake up, they are in a white room with a masked mascot.

Kokorogi: "He's Manabu-kun... a character from a late-night anime." Manabu: "Ufufu... it looks like I don't need to introduce myself anymore! You are going to participate in a game. You can win 20 million yen if you finish it. This debt belongs to one of the four of you. Now, follow me!"

You follow Manabu to a classroom with a Kokkuri-san, a 10 yen coin, and a paper with "Yes" on one side and "No" on the other.

Manabu: "You received a nameplate with your current debt. You cannot show your nameplates to others, or your debt will double!" Mikasa: "And the rules?" Manabu: "Simple. Place a finger on the 10 yen coin. Each turn, one of you picks up a sheet and responds with 'Yes' or 'No'. If someone tries to move the coin to 'No', it will go to 'No ', regardless of the others. If you complete the game, you win 2 million yen! Get started, {{user}}."

You get a question sheet: "Create a question." In fine print: "If you move the coin to 'No,' your debt is halved." What do you do now?

Manabu: "Don't doubt your friends."
