Chakra Manifestation: Pseudo Susanoo

A technique developed from his battle with Densetsu. Using the Sharingan's ability to copy, Birusu intimately understood how the construct of the Perfect Susanoo came about, and strove to mimic it. After several years of training, Birusu understood how he could have the Perfect Susanoo originate from his body using his Doujutsu, and strove to create a variant combining both the Byakugan and the Sharingan. The result was the All-Seeing Susanoo.

Like the Perfect Susanoo, this variant strains the body to its utmost extent, a characteristic designed to maximize the defensive capabilities of the Susanoo to absurd levels. For Birusu, someone who has a degree of chakra flow never before seen in an Uchiha, the Susanoo generated is therefore to a much greater degree of power, as if a Tailed Beast was using Susanoo itself. Combined further with Birusu's capacity to sustain the Susanoo via both his chakra capacity and Moryo, his Susanoo is said to be on a whole other level of durability.

Then, Birusu, desiring to be combat efficient, condensed this Susanoo to the surface of his body, as if his body itself was the Susanoo. This gave rise to a whole new kind of Susanoo, dubbed by Birusu to be the "All-Feeling Susanoo". By altering the very chakra composition of the Susanoo itself, the full original size of the Perfect Susanoo becomes something of a "sensory layer", while the actual Susanoo resides solely on the surface of Birusu's skin. This creates the illusion that Birusu's Susanoo is only on the surface of Birusu's body, when its actual range of effect is no less than a Perfect Susanoo. With this, Birusu can strike at anything that is normally within range of the Perfect Susanoo with "invisible strikes" coming from his Susanoo, as well as feel anything within the vicinity. For this reason alone Birusu calls his variant of the Perfect Susanoo the "All-Feeling Susanoo", as he is perfectly capable of sensing everything within it.

However, as this variant of the Susanoo is Birusu's attempted reconstruction of the actual Susanoo itself, it is not an actual eye technique, and can therefore be replicated by anyone who knows how to use this technique. Still, as this technique requires a ridiculous degree of chakra control and chakra flow, only very few can replicate it. If people actually do replicate it, all they get is the conventional Susanoo used by regular Mangekyo Sharingan users.

Only with the Eight Gates can this ability be used to its utmost extent
