The Wishing Games: Fairy-Tale's Truth

Three brothers get an invitation to move to another world called Wisher's World. When they accept, they are teleported into the world but are dropped into a lake. We meet a Were (the term for shapeshifter-[werewolf]) that tells us how the world works. We go on missions and buy a house to settle down in. A festival happens every year so we deiced to participate. Then a major problem arises that threatens the world. Jack the Giant Slayer (Jack and the Beanstalk), along with Harper (Harper Harpoon), and Tyus (Golden Goose), attack us at the festival and try to take over Wisher's World.
