Greetings, everyone! In a nutshell, let me introduce you to an exciting crossover project that combines the worlds of Pokémon, Made in Abyss, and Etrian Odyssey. This unique endeavor takes the form of a captivating dungeon-crawler with an immersive story. The best part is, you don’t require any prior knowledge of Etrian Odyssey or Made in Abyss to thoroughly relish this game!


On the island of Talrega lies the entrance to the Yggdrasil Labyrinth, a gigantic maze full of treasure that has attracted the attention of adventurers from all over the world.
What are you looking for? Money? Fame? Or do you just want to test your coaching skills by conquering the maze?
Is there something deep?
In this game you take on the role of Nyx, a young adventuress who wants to challenge the maze.
But as soon as she begins to descend, something goes wrong…
