I'm the new owner of a magical mansion. This mansion, well, it's not your typical building. It's a dungeon from another world, masquerading as just another private residence in the suburbs. It has enchanted rooms, can craft powerful items, build lethal traps, and produce incredible monsters. And it's my mission to protect and evolve its monstrous inhabitants.

Now that I've bonded with the mansion's dungeon core, I have a lot of work to do. Create new monsters. Build my dungeon. Prepare my team. And I have to do it all before the Technomancer comes for a visit. When he does, my mansion, my monster girls, and my creatures will be ready for him.
