Blackwater

Blackwater (Romaji: Burakkuuouta; Kana: ブラックウォータ) is a hex of the Despair Curse.

Description
Blackwater consists of the generation of an amount of despair and then the condensation of that despair into a destructive liquid which is crackles with darkness.

Notably, the liquid is more than capable of annihilating a supermajority of the entities that it is used against. In addition, the liquid exhibits the unique property of draining the hope from both whatever it comes into contact with and wherever it is located.
