Black Marlin

Black Marlin is a Teigu that takes the form of a Ring. It was formerly owned by River and is currently owned by the Revolutionary Army.

History
Black Marlin was created using a body part of a dangerous aquatic beast that had the ability to control water.

Abilities
The user can control any liquid around, including water and blood. However, it only functions in the presence of water or any other form of liquid around. Oftentimes, the water takes the shape of serpents.

Techniques

 * Water Cannons: The user collects water and shoots it in multiple streams at the target.
 * Snake of the Abyss: The user forms a giant snake out water and fires it at the enemy.
 * Evil Dragon Spear: The user quickly launches multiple pillars of water at a target.
 * Judgement of the Ten Heavenly Water Dragons: The user launches ten streams of water at the target in the shape of dragons. This attack seems to be very powerful.
 * Blades of Blood: The user manipulates their own blood in the form of blades to cut the opponent. This is this Teigu's trump card.
