Shūsen

is perhaps the most versatile defensive technique afforded to Hijiko via The Way of the Asura Path. It is a superbly complex barrier technique of extraordinary usefulness and is highly resilient to incoming forces. The technique can only be used by Hijiko due to his immersive understanding of the true nature of chakra and his The Way of the Asura Path. According to Hijiko, it is virtually impossible to impede the formation of this barrier and even more so to vanquish it after it is formed.

The spherical barrier grants Hijiko unparalleled protection against even the strongest forms of offense such as his own The Way of the Asura Path: Catastrophe at a point blank range and even Yōja 's planetoid sized Deep Crimson Spiral. The technique is extremely difficult to maintain from the users standpoint due to it requiring two arms to maintain it. Since Hijiko is able to have multiple mechanical appendages emerge from his back, maintaining the barrier is no issue. The barrier has the ability to absorb a boundless amount of energy and matter.

Whether the force is kinetic or potential, the barrier is able to absorb it thus removing any form of motion within it. Hijiko can also produce a larger barrier that inhibits the manipulation of chakra of those within its boundaries. The barrier can also be formed with a single hand but it only covers a single direction. However, it can be used as an offensive ram or to deflect attacks on the move does not hinder Hijiko's agility.
