HoloDungeon: Koyori vs HollowLive in Honsha Tower

Just as most of the meticulous planning was complete, the world suddenly transformed into the mysterious labyrinth known as the “HoloDungeon”.

The HoloDungeon is a dungeon that shifts its form like a hologram.
Layers are automatically generated, ensuring no adventure is ever repeated twice. A fresh and exciting experience awaits you every time.

If you fall in the dungeon, you will lose many things gained during that adventure, such as picked-up items and experience points.
However, the knowledge gained from that adventure will surely help you on your next one. Also, “Dungeon Experience Points” are not lost even if you fall in a dungeon, and the “Decorate Recipes” obtained by paying these points are also important keys to clearing the dungeon.
