Bunkōgan

The Bunkōgan (Spectrum Eye) is the second form of the Saigan.

Abilities
Unlike the Saigan, this one can manipulate Yang Release chakra and can use Yin-Yang Release through it's "multitasking properties".

Multitasking
While the Saigan can only use one element at a time, the Bunkōgan can use two at a time; one eye glowing perhaps green, while the other glows red (fire and wind). This allows a user to use two elements at a time, however, this is not to be confused with Kekkei Genkai, because the eye technique doesn't create a mix between the elements. Due to multitasking, one-hand sign weaving is an inherited ability, in order to simultaneously use different elements.

Other Abilities
The Bunkōgan slows-down it's user's point of view. The telescopic range of vision the Saigan already possesses is increased by 10 more kilometers. This includes the field of chakra sensing. Not only can it view chakra color, but it can distinguish human from clone, can break out of genjutsu, and increases the holder's reaction speed and co-ordination
