Gameplay:

Characters battle with hired devils known as Servan in the Game's RPG battle system. These demons, divided into assault and support categories, can be called upon during combat via SP. They earn new skills as they grow stronger in consecutive bouts. When not following orders to advance the plot or fighting adversaries, the player accepts tasks and customises at the hotel.

With each successful assault chain, Arnice, the Game's main playable character, gradually fills up a transformation gauge. Arnica may also land attack cycles using light, heavy, and special attacks. The player can start a transformation that will improve her attacking power when the gauge is full. Her rabbit form concentrates on speed and physical fighting, her devil feature enables her to control fire, and her ghost form enhances her recovery powers. Depending on the circumstance, she can also use her blood to create various blood-power weapons, like knives and longswords, which alter her attack repertoire and the capabilities of summoned demons.

The Game also features an alternative Arena where users can take on different tasks and receive rewards, including engaging in combat with unique limits and battling foes inside a maze.
