Status, honor, power. I've lost everything.
Before the embers of my life go out.... will you...
...become my royal strength...? -Lu
I'll retake the throne...
I'll give my soul for you...
The contract is complete. -Ciel
Having a duo character play-style, players have access to a special mechanic only available known as Switching. Players can play as either Lu or Ciel in both towns and dungeons, and change between them via pressing V (default key and only available where combat is possible), combos, or skills. When switching via the V key, the character switching out cannot be hit, but the character switching in can be hit and the combination gauge will not be filled. Cooldown time for V key is 1 second. Depending on the user's preference, it is even possible to play only as Lu or Ciel all the way until the end, but it will be more fun and efficient to change between characters, depending on the situation. No cooldown is implemented into the exchange mechanism but you will always start out as Lu when entering PvP or dungeons. You can choose to either defeat enemies with strong demonic magic as the melee Lu, with quick slashes and gun shots as the ranged Ciel, or utilize both to chain numerous combos.
