The Fay Slayer (or Fey Slayer) is the personal weapon of Neige Hausen. It's a big magic lance that's capable of firing both solid-based ammo and a devastating energy beam. The ammo can be bounced of several mirrors to hit the enemy from multiple angles. The blade on the business end of the weapon can be used for both slashing and stabbing, and has enough durability to withstand being planted in the ground and spin around on without breaking. Neige manages to use the weapon like a functioning guitar during her 'Veracious Mirror' and 'Cute Crown Breaker'.
