Longinus Prototype

The Longinus Prototypes were mass manufactured in Tenryūji for use by Yūmei. He keeps them contained within sealing tags contained within his garments and on his wrists for easy access. As part of the Longinus series, they are intended to be wrapped with Power Release chakra to achieve devastating effects.

Physically, the Longinus Prototypes resemble long, red bidents. Their structure is inherently double-helical (in its normal configuration), with the majority of its length being straight and composed of two strands which are tightly interwoven. At one end, the two strands unwind and form two massive tines.

While the bident is the spear's default shape, it also has metamorphic capabilities. The tines wrap together to form a seamless piercing object when thrown. Upon encountering a barrier capable of repulsion or deflection, the "flaps" of the spear open up, revealing white, gill-like structures that seem to aid the spear with self-propulsion under conditions of extreme resistance.
