Excavado (Spanish for "Hollowed Out"), incorrectly referred to as a Visored, is a highly experimental and corrupting form of Hollowfication that was thrust upon Shigeru Yūdai. It resulted from the joint experimentation of Kagura, Bansui, and Averian, using the former's Hōgyoku and the latter's unique abilities at the conclusion of the First Spiritual War. Sometime following the Collapse it was discovered that Shigeru, believed to be the first and only example of this occurrence, was not alone. Kentaro Hiroshi's Hollowfication was also a result of Averian's power, only he did not require the Hōgyoku to facilitate the process, as Kentaro's Hollowfication took place when he was in the womb, thus making his Hollowfication natural and Shigeru's unnatural.
