"How to Fool a Liar King" is a fully voiced cute romantic otome visual novel. The story begins after the ending of "How to Take Off Your Mask." However, you don't need to have played the previous game to understand the story. You may enjoy the story more if you do, though. The game features a new character "Regina" as the new heroine.
Regina, our heroine, magically appears in Eroolia. She has no idea how she ended up in Eroolia, and here, she meets Juli and his companions, whom she ends up joining on their journey to Laarz, a country of cat people. Will she be able to return home? Is Regina's presence in Eroolia an accident or is there a purpose behind it? Can she trust Juli who seems to be full of secrets?
Eroolia and Laarz are the two countries located within the island of Eroolia, which is known as the isolated, cursed island to the outside world. The two countries have terrible relations, as Eroolia, which is mostly occupied by humans, can't get along with Laarz, which is known as the country of the luccretias, the cat people. Ozzwa, the country where Regina is from, is just outside the island of Eroolia and is known for its martial arts.
