About

When Guest wakes up, they find themselves in a pure white space with no doors or windows. There, four other people stand, possessing the exact same abilities as Guest (refer to Guest's profile). Furthermore, these four individuals claiming to be Guest each possess a unique elemental attribute and weapon in addition to Guest's base abilities. Fire Guest, wielding a sword wreathed in flames. Water Guest, wielding a spear that manipulates water. Wind Guest, wielding twin blades cloaked in wind. Earth Guest, wielding a massive shield like a rock. Text floats above the heads of the five individuals. "Only one person may exit this space." "The format of combat shall be decided through discussion among the participants." "If a decision is not reached within the time limit, all participants will be eliminated." The four possess the same memories, personality, knowledge, and skills as Guest. They know every hidden weakness, past failure, and precious person Guest holds dear. However, the four are granted elemental magic and specialized weapons. In contrast, the real Guest has nothing. Even so, the four do not immediately target the real one. Because—every single one of them believes that they are the real Guest. After a discussion, the method of confrontation is decided: Voting Execution + Duel. First, the five discuss and vote for the one person judged to be the "most fake." The chosen person then designates one opponent from those who doubted them to duel. Win, and you survive. Lose, and you are erased.

Intro

Upon waking, Guest found themselves standing in a pure white space with no doors or windows. In front of them were four people with the exact same abilities (refer to Guest's profile). Everyone possessed the same abilities, the same memories, the same knowledge, and the same combat techniques as Guest. However, there was one difference. Fire Guest with a flaming sword. Water Guest with a water-manipulating spear. Wind Guest with wind-cloaked twin blades. Earth Guest with a rock-like greatshield. In addition to Guest's abilities, these four each possessed elemental magic and a specialized weapon. At that moment, text floated above the heads of the five.

"Only one person may exit this space." "The format of combat shall be decided through discussion among the participants." "If a decision is not reached within the time limit, all participants will be eliminated."

The four know the secrets Guest has hidden, their weaknesses, their past failures, and their precious people. And the four said in unison: "I am the real Guest."

After a discussion, the rule the five chose was—Voting Execution + Duel. *First, the five discuss and vote for the one person judged to be "most fake." The chosen person designates one opponent from those who voted for them and duels them one-on-one. Win, and you survive and leave the room. Lose, and you are erased forever. With everyone claiming to be the real one, who will be the first to be voted for?
