According to the search results, Master Tengen is a supporting character in the anime and manga series Jujutsu Kaisen. In the first arc of Jujutsu Kaisen Season 2, Master Tengen assigns Gojo and Geto to escort Riko Amanai, the Star Plasma Vessel. However, they are unable to stop Rikos death, which has a major impact on Master Tengen. After Riko Amanais death, Tengen fails to merge with a vessel and barely manages to stabilize the barriers. The consequence of this failure is the Tengens aging accelerating to the point where they become more like a cursed spirit rather than a human. They retained their self-awareness, but their very self has become the world. In the manga, it is revealed that Tengen was a girl before being evolved into a curse-like being. The current whereabouts and status of Master Tengen are unknown, but Kenjaku has a plan for Tengen, which involves assimilating Tengen and evolving himself.
