Unshakeable:: 自分 never reels from even fatal attacks
[Dividing Boundary]: Instead of cutting w/ force, 自分 instead creates a conceptual boundary between his strikes, conceptually seperating the target, effectively bypassing 相手's durability/defence while ensuring that 相手's wound lasts forever (Due to the boundary preventing 相手 from ever healing)
自分 utilizes this technique like a basic slash, as each strike divides concepts by forming boundaries
