Double Sword Style

This technique is used by the Organization number 11 Undine (former) and Deneve (former 15) later takes up Undine's sword after her death and uses the same technique.

Usage
Undine uses her Yoki to enhance her muscles, giving her monstrous strength and a bulky appearance. However this is only temporary as she reverts to her small and delicate form when she stops using her Yoki

Following Undine's death, Deneve took it upon herself to carry Undine's sword and practice using it to great effect. She is able now to augment her strength to wield the two swords effectively without using Yoki.
