Looks: The casual mask would be blank and white. When fully formed..it has some slanted, curvy cut out eyes for Yukimura's black and yellow eyes to peer through. A dark blue water droplet appears below his right eye and black wind currents covers both cheeks of the mask, almsot resembling some loose clouds. He also has some visible fangs that appear to overlap the mouth.
Inner Hollow: The inner hollow actually appears to be an evil bookw ith an ominous aura. However, upon the relase of his zanpaktou, depending on Shikai and Bankai, it becomes a stick figure..and then finally, a dark spectrum dragon that resembles the one on his bandana.
Powers and abilities: Along with the casual increase in speed and power, in shikai, he also gains the ability to have his reiatsu to create and form 'pores' to catch the air..giving him temporary control of the wind. When in bankai, not only he gains wind, but he may only catch enough moisture in the air to make and control water.
