Mink is Belphegor's Storm-attribute Box Weapon. The Storm Flames on its tail have disintegration powers, because of the Storm Flame's Disintegration characteristic. It is modeled after the mink, an animal that belongs to the weasel family. Oddly enough, it resembles Belphegor in both looks and attitude.
- Frictional Flame Production: Mink can produce Storm Flames through frictional heat when objects rub against its body.
- Tail Shield: Mink can create a shield of Flames by concentrating its Storm Flames on its tail and then quickly spinning it.
- Fiamma Scarlatta (Crimson Flame): Mink creates a large wall of Flame that can instantly wipe out several enemies.
- Bel Dive: An attack that combines the Flames of Mink and Livya. Mink jumps onto Livya and emits its Storm Flames to combine it with Livya's Lightning Flame. Livya then dives towards the enemy.
