Han

Han (反, Han)

Zanpakutō
Gū (ぐう, Guu) - The blade's appearance is unknown. From the outside, it appears as a normal katana, but since it is never unsheathed there is no certainty it even has a cutting edge.
 * : Gū is released with the word Fall (倒れる, Taoreru). The blade doesn't need to be unsheathed to be released, an uncanny feature which says a lot about Han's soul.
 * Shikai Special Ability: When Gū is released, it rains. There is no definite formation of clouds, hinting that the source of the rain is merely Han's reiatsu. Gū has a range enough to cover a quarter of Seireitei, and everything touched by the rain is under its influence. It seems the rain can pass through any non-intelligent object if Han wishes it to do so, making sheltering under anything but another individual useless.
 * Ichinen (一念, time of single thought; determined purpose)
