Typhoon refers to a storm that occurs in the tropical waters of the northwest Pacific Ocean that ranks 8 or above on the Beaufort Scale (39 mph or above wind speed). This temperament is appropriate for Iku as she is the messenger of the dragons and tells of coming calamities. Iku is endowed with Wood Phase representing the air and lightning, and Moon Essence representing her ability to cross barriers. The strong and kind Wood Phase resists Water Phase, because water nourishes wood, but it is weak to Metal Phase, because metal carves wood. The cooperative and indecisive Moon Essence resists the alluring and arrogant Sun Essence, but it is weak to the diverse and uncooperative Star Essence.

Iku Nagae's ability as a messenger of the Dragon Palace. It allows her to, by every meaning imaginable, read the atmosphere. "Atmosphere" has many meanings in Asian languages, and Iku's ability is thought to apply to as many situations. Though it differs in form somewhat, Meiling's ability is similar to Iku's in some ways. Iku's ability allows her to immediately grasp the context of a situation and smoothly insert herself. Perhaps her ability is more related to mood than atmosphere. Maybe reading a room is evident in her gentle manner and her politeness... but this side of her is not always present while she is on a mission. The ways she carries herself in battle, including her ability to so effortlessly dance through her enemies' attacks may be because she is skillfully reading her enemies' fighting spirit. Her command of thunder and lightning may also be related to her reading the atmosphere because they are a product of the atmosphere surrounding the planet. Electricity is energy of the Wood Phase, as is the wind, meaning they both share a root origin in the flow of air. If that's the case, then the atmosphere that Iku controls may not be limited to the Wood Phase, but because such a thing has not been directly observed, there are no details to speak of. Atmosphere is an invisible force that affects everything within it, much like the atmosphere around the Earth that traps air within it. Air may be the atmosphere closest to us, and by breathing it in, we take the atmosphere itself into our bodies. Because of this, in ancient times, breathing was considered the bridge between the air of the outside world and the air inside the body. Iku's ability to read the atmosphere (or air) may be more closely linked to these two kinds of air... maybe.
