Togabito Race Information

The soul of a dead Human normally passes on to the Soul Society with the assistance of a Shinigami. However, Humans that lived lives full of sin including those that become Hollows after dying are incapable of entering the Soul Society.
Instead, they are sent into the depths of Hell, where they are bound by indestructible chains and condemned for the rest of eternity. Under ordinary circumstances, these Togabito are incapable of leaving their prison, for they are constantly watched over by Kushanāda, the guardian of Hell.
However, some Togabito are capable of leaving Hell and entering the Human World, though they apparently need to conceal their faces to prevent Kushanāda from dragging them back into Hell. Some Togabito possess immense amounts of power, which can surpass that of even an Espada.

Whilst in Hell, the Togabito live through a constant cycle of rebirth, death and regeneration. After a being is killed in Hell, their bodies are enveloped in chains, which sparks the transition into a Togabito, ultimately trapping them there due to the sturdiness of their chains. Also, the strength of each particular Togabito is the primary factor which influences their rate of regeneration.

Incarcerated in Hell, Togabito commonly have white garb with thin black stripes, though certain Togabito have been shown to have their own attire.

While out of Hell, most Togabito have variations of one standard set of clothing, which is a black cloak with white rectangular buttons, draped across their entire bodies, concealing their physical makeup.
Also, the Togabito share the same mask, which is light bulb-shaped and split off diagonally with the color of black and white. Their limbs are covered by white gloves and boots.
The purpose of the mask and cloaks are to conceal the Togabito from the watchful eyes of the Kushanāda; however, at the same time, the cloaks hinder their power to some extent. Should too much of this garb be removed, the Kushanāda will immediately be alerted to the Togabito's escape and will immediately chain up the Togabito and drag it back through the gates of Hell, where the Kushanāda will promptly punish it and then lock it in the lowest levels of Hell.
This is why Shuren wears bandages underneath his mask, in case somebody breaks off his mask. For unknown reasons, Kokutō has been shown to exit Hell freely without this attire. It should be noted, however, that he kept parts of his face obscured behind black bandages.

Most Togabito often feature chains as part of their outfit. While usually they appear relatively short, these chains often extend further than they appear, as Kokutō has demonstrated.
These chains are a part of the force of Hell that is incarcerating them, and are nearly impossible to destroy. The Kushanāda are capable of grasping the normally invisible lengths of chain to drag the Togabito in.
While they are a great inconvenience for the Togabito, the chains can have multiple useful purposes, as demonstrated by Shrieker and Kokutō.
Since the chains are nearly impossible to destroy, one can use the chain to block attacks from someone without the necessary power to destroy them.
