Kenjutsu: Nebularaid Empress

A hidden technique that Yuhara learned and mastered on her own. She likes to call it an Arcane Sword Technique although her sister laughs at that name.

Overview
Yuhara's control over chakra is a key to using this skill. Not even her sister is able to use this skill without a few months or so of training. Yuhara imagines five rows separated by a wall on her left sword, almost like a container. She flows elemental chakra from each of the five basic nature transformations into the five rows. She then imagines her right sword split in two by a wall and flows Solar Release and Lunar Release into it. She then performs a 22-hit attack. (Refer to the image to find out the details and yes, I took it off of SAO: Hollow Fragment; Sue me.)

Trivia

 * Nebularaid Empress is but one of a series of techniques that have the same names as some sword skills from SAO: Hollow Fragment.
