The Sagittarius Vertex (サジタリウス・バーテックス) is an enemy of humanity, and the second Vertex the Hero Club encounters. It is based on the constellation Sagittarius, the Centaur.
Blue and wheel-shaped, with two 'mouths,' and a thin projection connecting its two lowest points.
This Vertex's upper mouth can charge up a single, concussive, long-range shot in the form of a narrow spear.
This Vertex's lower mouth can fire hails of needle-like projectiles.
This Vertex serves as long-range, high-damage assault for the trio of the Scorpio, Cancer, and Sagittarius Vertexes. The power and range of the Sagittarius Vertex's attacks make it a force to be reckoned with, but when united in its trio, it becomes exponentially more deadly. With two other Vertexes to draw fire, it is free to unleash a deadly barrage; the Cancer Vertex's six fan-like projections can reflect/redirect the Sagittarius Vertex's hails of needle-like projectiles, allowing it to fire at angles which would be otherwise impossible, such as around corners, in different directions simultaneously, and at multiple targets.
-This Vertex's needle-like projectiles glow as though they are hot, or comprised of energy. However, they can be seen lingering when lodged in Karin Miyoshi's Mankai.
-This Vertex's soul is located within its lower 'mouth' ; its interference tactic is blinding speed. Upon emerging, this soul orbits the Vertex's main body incredibly rapidly, becoming nothing but a blur. With precision timing, Mimori Togo destroys it with a single shot. Itsuki Inobuzaki: "Did Togo do that?" Fu Inobuzaki: "Yeah, she nailed it!"
