Harem Dancer appears as a boss in The Answer on the 14th floor of Caina. It comes accompanied with 2 Merciless Mayas. The Shadows must be beaten to continue. These shadows will attempt to Poison or Distress the party during the battle, but while one effect is active, the other ailment may not be added. Poison will slowly drain the party's HP per turn, but Distress will lower evasion to zero and increase the risk of Critical Hits. Leaving the party poisoned may be preferable to constantly using Dis-Poisons or allowing the shadows extra turns. Once alone, the Harem Dancer will begin using Marin Karin to charm the party members.
After being defeated, the Harem Dancer will drop the Ebon Heart barter item.
Harem Dancer appears in Worlds 4 and 5 of Magatsu Mandala within the Midnight Channel. Upon being defeated, it may drop a Love Clasp. Selling 4 Love Clasps will unlock the Hototogisu ougi for Yukiko Amagi in the shop.
In Golden, Harem Dancer appears in Worlds 2 and 3 of Magatsu Mandala within the Midnight Channel. It can buff itself with Heat Riser, and attacks with a medium single-target physical skill. Its critical rate is increased due to its passive Apt Pupil.
