Mūbiki

"I thought you were supposed to be one of the good guys." "I thought you were supposed to be one of the smart guys."

- Mūbiki

Mūbiki (無響, Muubiki; literally "Anechoic") is the leader of Setsudan and the current incarnation of a figure that has appeared across all spiritual dimensions hundreds of times over the last millenia. The earliest known record of his existence is as one of the founding captains of the, although there is no solid evidence that this was his first incarnation.

Due to the, Mūbiki became an exception in the spiritual cycle, being forced to retain every aspect of every single life he ever lead. The accumulated sorrow and pain, as well as the sensation of the happiness he had attained being ripped away from him countless of time gave birth to Setsudan, and their goal to eliminate the. Through this, Mūbiki believes that he can halt the process of life and death and finally be able to be at peace.

Appearance
Mūbiki has the appearance of a young teenage boy, implying that he hasn't possessed his current form for too long. He has medium-long, black hair which covers up his left eye most of the time. His eyes are a dark purple, although their saturation has shown to differ on separate occasions, ranging between a light orchid to pure black.

Mūbiki seems to favor wearing a black blazer with a crimson hem, accompanied by an equally dark pair of trousers. In comparison to most characters, however, his attire has been shown to be very extensive, so it's not really determinable what it usually consists of. In reminiscence of the woman he loves, he still wears his wedding ring, although he himself isn't even sure how much time has passed since she passed away.

Powers & Abilities
The sheer fact that he was able to go toe-to-toe with the legendary is a testament to his power, even if he lost his life in said battle. The accumulation of sorrow throughout his lives tainted Mūbiki's spiritual energy to the point it devours any living being that comes within his vicinity once released, forcing him to suppress it continuously if he doesn't want to destroy his surroundings. His reiatsu is purple in color.

He has shown to be able to direct the destructive nature of his reiatsu onto specific targets, allowing him to disintegrate numerous Gotei 13 officers within the crowd-packed streets of the without harming any bystanders. Mūbiki can control the different aspects of his reiatsu meticulously, being able to make it dense enough to block physical attacks in mid-air or making it cover an area as gigantic as. Despite his massive resources, he can disguise his spiritual signature to the point even the most experienced trackers lose sight of him - this is what allowed him to spend many of his lives in Soul Society without anyone recognizing his presence.
 * Tracking: Mūbiki can sent out a ripple of his spiritual energy that, while visible upon creation, travels through the entirety of the dimension unnoticeably. This allows him to pin-point any specific target whose spiritual signature he's familiar with, no matter their location. He can even sense other creatures across dimensions given sufficient concentration. His knowledge of tracking methods allows him to circumvent similar efforts by his foes completely. If Mūbiki ever is detected, it is probably because he wanted to be.
 * : A technique which he developed to have a better chance against Yamamoto, Mūbiki can use his own overwhelming spiritual pressure to brake the movements of spiritrons around him, causing any technique or opponent to struggle in moving forward. The potency of this technique allowed him to retard 's flames to the point that they could be avoided at a walking pace.

Immense Strength: Although showcased only at specific points during his lifetime, Mūbiki has shown to be in possession of a very high level of physical strength. This trait is possibly the least he developed across his life spans, due to it having to be re-evaluated with every new body he attained. A single punch of his could overturn a concrete floor completely, the force of which was enough to crack nearby buildings as well. During his lifetime as a Gotei 13, he was noted as one of the few who could take on in a contest of sheer physical strength, a feat few after him have ever rightfully claimed.
