Qisha Tianling is a sentient demonic sword that appears in the anime Chaos Dragon: Sekiryuu Seneki. It is the weapon carried by Lou, whose full name is Zhenhua Lou, a representative of Kouran within the Red Dragon Expeditionary Group. Before joining the expedition, Lou served as an assassin for a religious organization in Kouran, and Qisha Tianling is the blade she came to wield.

The sword is known for its enchanting nature, capable of bewitching those who lay eyes on it. It is also a soul-drinker, absorbing the souls of those it has killed. Beyond its physical properties, Qisha Tianling possesses its own will and voice. It can speak to its wielder and issue commands, and it does so when those commands serve its own interests. This self-interested and commanding demeanor is central to its personality, as it treats its wielder less as a partner and more as a servant acting on its behalf.

Lou addresses the sword as her Lord or Your Highness, which reflects the power dynamic between them. The sword's guidance and demands shape her actions, making it not merely a tool but an active influence in the story. Its role is that of a supporting presence, directing and steering the assassin who carries it and acting according to its own desires rather than any external allegiance.

In terms of abilities, Qisha Tianling combines supernatural allure, the capacity to consume souls, sentience, and the authority to command its wielder. These traits mark it as a demonic and dangerous artifact whose loyalty is ultimately to itself.
