Qi Sha Tian Ling, also written as Qisha Tianling, is a sentient enchanted sword that appears as a supporting character in the anime Chaos Dragon: Sekiryuu Seneki. Rather than a conventional human character, it is a self-aware weapon with its own will and voice. In the original material it is classified as a yōken, a bewitching or demonic blade, and its behavior reflects that designation.

The sword possesses an enchanting quality that bewitches those who see it. It absorbs the souls of those it has killed, and it is able to speak to its wielder, issuing commands whenever doing so serves its own interests. Because of this, its personality comes across as commanding, manipulative, and thoroughly self-serving, treating its bearer not as a master but as a tool for carrying out its will.

Its central role in the story is bound to Lou, the character who carries it and refers to it as her Lord. Qi Sha Tian Ling exerts a strong influence over Lou, directing her actions through its spoken commands and using her as the means to pursue its own ends. The relationship is therefore one of control, with the sword acting as the dominant presence in the pairing.

In terms of abilities, Qi Sha Tian Ling has the power of enchantment, allowing it to charm and beguile those who look upon it; soul absorption, enabling it to consume the souls of the people it kills; and sentience, which grants it speech, independent thought, and the capacity to steer its wielder. These traits make it a sinister and influential presence within the story even though it functions primarily as a supporting figure rather than a central protagonist.
