Tengen ( (てん) (げん) Tengen?), often referred to as Master Tengen ( (てん) (げん) (さま) Tengen-sama?) is a supporting character in the Jujutsu Kaisen series. They are an immortal jujutsu sorcerer that remains within their chamber; the Tombs of the Star Corridor at all times in order to reinforce the barriers that protect both Jujutsu High locations.

Master Tengen is also known as the "Star" ( (ほし) Hoshi?). They were responsible for preaching the foundation of jujutsu sorcerers and spawning religious groups that worship the Star as their deity.


Due to the nature of Tengen's role in the jujutsu world, most people have no idea what they look like. Only those granted permission have seen that Tengen does not quite possess the appearance of a typical human being. Tengen has four eyes with a cylinder-shaped head that features no hair at all, but they do possess a bipedal humanoid body. They wear a simple light-colored robe.

As stated by Tengen, due to Toji Fushiguro killing the previous Star Plasma Vessel 11-years ago and unable to fuse with her, Tengen's current appearance is the result of him having continued to "evolve" past his humanity. This in turn implied that Tengen himself originally possessed a much more human appearance.


Tengen appears to be a well-mannered, straightforward, and knowledgeable individual with humanity's best interest in mind. They don't seem to mind awkward questions about their experience and is more than happy to help normal jujutsu sorcerers provided the right situation.

Tengen was willing to do all they could to help Yuji and the others stop Kenjaku, but in return asked that two members of his team remain behind to protect them as well. They were stern about this point, but only because Tengen's own safety is the key to humanity's survival.


Overall Skill Level: While Tengen does not interact with the outside world or go on missions, their abilities have been essential to protecting the pillars of the jujutsu world for thousands of years.


Innate Technique
Immortality (不死 (ふし) Fushi?) is an innate technique that grants Master Tengen eternal life, however, it does not stop the aging process.[1] Tengen doesn't have an issue with aging but must reset their body every five hundred years by merging with a specific human being in order to prevent the technique from causing him to evolve past humanity and into a potentially dangerous state.[2]
Barrier Techniques
Master Tengen powers both barriers that protect the jujutsu schools and strengthens barrier techniques used by the school's auxiliary managers.[3] Their barrier technique changes the building's appearance every day and effectively hides the existence of the schools. The cursed storehouse is also protected by a barrier that manipulates over one thousand doors while only one is connected to the storehouse that contains the cursed objects.[4]

However, Tengen's barrier is for hiding rather than protecting and is ineffective once infiltrated. As long as you know the location of what you're looking for, the barriers are not difficult to maneuver through.[5][6]

The corridor of the star where Tengen resides is the base for all barriers in Japan. The barrier around Master Tengen's room is protected by a different barrier than the one around the schools and only those invited may enter.[7]
