LARP, which means Live-action Role Play Game, is an interactive game that requires players to engage in role-playing and collaborate to solve puzzles. In these games, players are assigned different roles, each with unique backgrounds, motivations, and secrets. The storyline is often filled with twisted plots and shocking twists, requiring players to gather clues, analyze dialogues, and interact with one another to deduce the truth.

"If I Die Today" is a script centered around the famous painter Vincent van Gogh. The entire narrative is divided into two parts. The first part is a dream phase where players' identities are temporarily unknown. They must complete various tasks to obtain items, ultimately regaining their identities and defeating an evil demon.
