Exhilarating roguelike action with monsters and swords at your command
A world where a huge castle suddenly appears.
The protagonist, Rustil, who has no memory of his past, is drawn to the labyrinthine castle.
Choose your favorite ability from the souls of the heroes lying in the labyrinthine castle and acquire it.
Enjoy a variety of combat styles with one-handed swords, magic staves, gunblades, and more!
A mysterious labyrinthine castle that changes every time you enter!
Explore its ever-shifting corridors to collect powerful equipment and recruit monsters to join your team!
Choose Your Play Style:
Safe Mode
A casual exploration mode perfect for relaxed adventuring.
Even if your exploration ends in failure, you’ll keep all the items you found.
Challenge Mode
A high-stakes mode for those seeking thrill and reward.
If you're defeated and fail to return, you'll lose all the items you were carrying.
However, the risks come with greater rewards—rare equipment drops more frequently, and it's easier to capture high-stat monsters.
Note: Even if you lose equipment, you may be able to buy it back from the merchant at home.

All monsters in the game can be captured.
You can not only improve their abilities, but also decide their personalities in detail!

You can enjoy a variety of actions such as one-handed sword, magic staff, and bayonet!
Collect rare items and capture the labyrinth castle!
