A ninja to the core, Mizuki is efficient, logical, loyal, and emotionless. Not one for wasting her time, Mizuki rarely sees the point in idle chatter. The sole exceptions to this are her sister Kate, and her partner, Akaghi. By the way, if you're wondering if she and Akaghi are an item, she's still thinking.

While she has difficulties figuring out if she has a love life or not, she has absolutely no problems taking out the duellers of Middle. With speed and grace befitting a ninja such as her, the Shrike Rune user of the Island Republic is as deadly as the descendants of her craft.
