The Vestment of Extinction (断絶の斎服, Danzetsu No Saifuku) is battle reglia constructed by the infamous scientist known as tobikiri. As a hero uniform that was deemed much too dangerous, powerful, and destructive to ever actually be worn by a hero, the vestment of extinction went sealed away for many years in the depths of dr. tobikiri's laboratory, up until the raiment corporation incident, where tobikiri had no other choice but to let the hero costume bond with nagoya on a biological level, making him its owner.
