In Tōsen's case, his entire upper body had adopted a variety of accessories in addition to the mask, coating his entire torso. In a complete Hollowfication state, the Visored generally manifests more than just a standard mask. Of course, by his own claim, he is still far from mastering this power, requiring that he be pushed into his Hollowfication by an external opposing power, like the Quincy reiatsu that was protruding from Yhwach during their fight. Similarly, Ichigo Kurosaki eventually managed to tread onto this domain after reforging Zangetsu, claiming that his Quincy side and his inner Hollow finally found balance within him. This single-minded drive that transcended his understanding of Shinigami and Hollows is what allowed Tōsen to achieve a perfected Hollowfication. Whatever the case, Tōsen was a unique being that completely accepted the role of a Shinigami and the power of a Hollow, all for the sake of exacting his vengeance. However, it is also possible to say that this desire to transform into a Hollow was born from an unbridled hatred of Shinigami themselves. As such, what can be ascertained from Tōsen's words is that he desired himself to abandon the realm of Shinigami and become a Hollow itself. Tōsen considered it narrow-minded to say that moving further away from Shinigami and closer to a Hollow was corruption, calling that sort of argument "two-dimensional thinking that separates Shinigami and Hollows into good and evil". This is shown prominently in Kaname Tōsen, who displayed a perfected Hollowfication that was produced with the help of Sōsuke Aizen and the Hōgyoku. When the two sides of the soul manage to find balance, the two flow into one another and become a complete entity, which leads to the completed form of Hollowfication. These limitations of Hollowfication only exists as long as the Shinigami and Hollow aspects of the individual's soul remains in conflict. Similarly, some Visoreds only wear their masks while using Shikai and sticking to that method, but even then, the time limit is still only a couple of minutes at most. The strain of attempting use of the mask while in Bankai is so much harsher that most Visoreds avoid combining them together in combat, opting to unleash their Bankai without wearing their masks. This is shown especially among the former Captains and Lieutenants of the Gotei 13, who were only able to access their Hollow masks for a strict number of seconds at a time while only accessing their Shikai. Hence, a standard Visored is almost always confined within a time limit in which they can wield their Hollowfication in the form of donning a mask, before the power dissipates. Because the two forces are at odds, it stands to reason that they cannot cooperate for an extended period of time, before excessively straining the Visored's stamina and energy reserves. In order for them to draw upon the power from one source, it often means limiting or outright ignoring the use of the other. Even though they have avoided the dangers of soul suicude, they still remain an entity composed of two uncooperative aspects their Shinigami self and their Hollow self. Hybrids such as Visoreds exist in an unbalanced state of existence.
