Double Sword Style

Undine (the Organization's former No. 11) is the first one shown to utilize this style, earning her the title "Undine of the Twin Swords." Later, Deneve (the Organization's former No. 15) adopts this style in honor of her fallen captain.

Usage
Undine constantly releases her yoki to enhance her muscles, giving her monstrous strength and allowing for the use of two swords. Releasing yoki also gives Undine the bulky appearance she needed to get the Organization's approval in having two swords.

Following Undine's death, Deneve took it upon herself to carry Undine's sword and practice using it to great effect. At present, her strength is enough to wield the two swords effectively without using yoki.
