"Liar Liar - Episode 6" unfolds an intense tabletop treasure hunt between Hiroto Shinohara and Akizuki Noa, with their respective partners hidden inside the school building. The episode takes place at Eimei Academy, where the characters are embroiled in a strategic battle that demands not only intellect but also deception and unique abilities.

The game begins with Akizuki challenging Hiroto to a round of tabletop treasure hunting. The rules are explained, and the game starts with both players asking yes-or-no questions to determine the location of their opponent's hidden partner. They can also move across a virtual map of the school and use special commands.

Akizuki's aggressive playstyle and her use of the special ability "Double Action," which allows her to take two consecutive turns, put Hiroto on the back foot. However, Hiroto's partner, Saionji, helps him understand the rules and devise a strategy. They realize that Akizuki's abilities are likely illegal and decide to fight fire with fire.

As the game progresses, Hiroto cleverly uses the air conditioning to locate Akizuki's partner, Himeji, and appears to have won. But Akizuki reveals a shocking ability called "Alter Fate," which erases Hiroto's answer and turns the tables once again.

In a stunning twist, Hiroto reveals that he used an ability called "Pinch Hitter" to switch places with Himeji, making her the player instead of him. This means Akizuki's victory over Himeji transferred the cursed abilities of Himeji's device to Akizuki's, freeing Himeji from the curse.

Defeated and disheartened, Akizuki confesses her desperation to become something special and her fear of the "devil," Kurahashi Mikado, the director of Seijo Academy. She had made a deal with him to cheat Hiroto and steal his stars in exchange for making her dreams come true.

Hiroto assures Akizuki that he will deal with Kurahashi and encourages her not to give up. The episode ends with a sense of resolution and the prospect of a confrontation with the mysterious Kurahashi.
