Muen Kuchiki

Muen Kuchiki (無援朽木 Kuchiki Muen lit:helpless decayed tree) is the 3rd seated officer of the 6th Division, under the current head of the Kuchiki Clan, Byakuya Kuchiki, who is also coincidentally his uncle. He despite his tremendous abilities which are on par with even his uncle, prefers to stay in his position, saying, he doesn't ever want to hold back. He is currently on an assignment in the human world, tracking down the Quincy Taiyo Ankoku, as well as his gang. He is the future head of the Kuchiki Clan, and is also the supposed 'rival' of the 2nd Division's lieutenant, Jiao Yan. He wields an exceptionally rare zanpakutou as stated by the Soul Society, only appearing once every 5000 years, considered even rarer than the legendar Hyorinmaru. He is known by many as the Unwavering Spring.
