The Yōma's Nest is a mode in Senran Kagura 2: Deep Crimson where you do a series of missions arranged in a 14-floor pyramid. You can obtain EXP and Weapons as you press further. However, if you lose, you'll lose almost all of your gained EXP.
Each time you clear a room, you get to pick from two of the rooms below it on the next floor. Each room will have between 1 and 31 enemies that you must eliminate to proceed, though they may not all be in the room at once and instead spawn in as you clear enemies.
You can restart from any room you have previously cleared, or the two below it.
