Demon's Extract

History
Demon's Extract is a Teigu that gives it's user the ability to manipulate ice. It is speculated by Boss to be the strongest of all the Teigu. It's physical form is a chalice of black liquid, once it is consumed, a tattoo appears on the user's body. This Teigu cannot be removed once applied, and it also has a dangerous side effect, causing the user to hear dark voices that drive them mad if they do not possess a strong will. The user is able to summon and manipulate ice even without a nearby water source.

Esdese uses the Teigu to perform feats such as freezing an entire lake in an instant, using the frozen surface as a makeshift bridge to cross over and pillage the targeted village. Although after using her powers to this extent, she requires time to rest before using them once again. She is also able to create large pillars of ice to throw at enemies with devastating results.
