Seken


 * "Not even God would turn his back to this sword." - Kai no Kimi

Seken (背剣, Seken; lit. "blade's other side") is the pseudonym of the current leader of the Kuromaku Agency, who's actual name is kept unknown for safety measures. To date, he has been the only leader and was said to be "imported" from across another universe to ensure he would be unknown to anyone within the.

Personality
During his first appearance, Seken was portrayed as quite a mysterious character, mainly due his working status and such. His overall temper was quite ruthless, cold and silent, quite standard considering his position. However, later performances disproved this emotionless attitude, showing Seken is actually quite a "normal" guy during his free time. He compares himself to a vitalist, above all in their life-long promise to enjoy their life to the fullest and live as intense as possible. He has shown a general care-freeness and a staggering sense of unusual intellective and creativity, enjoying long philosophical conversations about hardly disputable subjects. He views his own being as unique and irreplaceable, but also weird in a way, and likes to compare his unorthodox view of life to that of "normal" people, even though he has no real interest in their opinion.

As mentioned above, his easy-going attitude is completely missing during battles or missions, being as professional and strict as possible. Seken is a guy whom will always follow the rules and never do something not "according to the book", as it is his very job to prevent people from making that mistake. Shutting his emotions and personal influences off, his only concern is completing his "job" as soon as possible.

Zanpakutō


Mūseiu (無政府, "absent of ruler") is the name of Seken's zanpakutō. In it's sealed state, it takes the form of a uniquely shaped pair of blades, which's likeness is said to be unlike any other within the spiritual planes. The blades are quite long, each one bearing the same length as a traditional katana, but being much slimmer and possessing a more discernible curve. There is no sign of a tsuba, and a simple exaltation and difference in colorization is all there is to indicate the beginning of the hilt. This hilt is gray-silver in color, while the actual blade is a pure silver. Mūseiu's metal doesn't seem to reflect like other swords, allowing for more unseen draws within the darkness and such.

The blades are held in a quite irregularly shaped sheath aswell, looking more like a rolled-up cloth strapped on Seken's back, where one blade is mantled from above and the other from below. However, the scraping sound whist unsheathing does suspect that an actual, bottomless sheath is hidden underneath.
