Question 1

What is Master Tengen's cursed technique?

Accepted Answer

Tengen's innate technique is Immortality — it prevents death from natural causes but does not stop aging. As Tengen's body ages past a threshold, the technique begins evolving it beyond human form. The reset requires a merger with a Star Plasma Vessel every 500 years. When the 2006 merger failed, Tengen's evolution continued unchecked, producing the four-eyed, non-human form seen in the manga.

Question 2

Why does Tengen stay in the Tombs of the Star Corridor?

Accepted Answer

Tengen never leaves their chamber because their existence is the foundation of Jujutsu High's security infrastructure. The barriers protecting both Jujutsu High schools and every auxiliary manager's barrier technique are powered and maintained by Tengen's presence. Leaving would compromise the entire system. Tengen is also a non-combatant — physically going out into the world would expose them to a threat they are not equipped to handle alone.

Question 3

How old is Master Tengen?

Accepted Answer

Tengen's origins trace back to the Nara Period of Japanese history, which places them at over 1,000 years old. Since the Nara Period predates the Heian era — when Sukuna was alive — Tengen is potentially older than the King of Curses himself. Kenjaku, who may be the only character older than Tengen in the manga, has known about them since the Nara Period.

Question 4

What was Kenjaku's plan involving Tengen?

Accepted Answer

Kenjaku's goal was to merge Tengen with all of humanity in Japan — using the Culling Game to gather enough cursed energy and willing vessels to trigger a forced evolution. The result would be a new collective species without individual consciousness. Tengen themselves warned that the completion of this process would likely kill every person involved. The entire Culling Game arc exists as a mechanism to make this merger possible.

Question 5

Is Tengen male or female?

Accepted Answer

Tengen is referred to with neutral pronouns throughout the manga. They were originally female — Tengen refers to themselves as "granny" in Chapter 202 — but centuries of body evolution and multiple mergers with Star Plasma Vessels have made any binary gender categorisation meaningless. The manga uses "Master Tengen" and treats their identity as beyond those distinctions.

Question 6

Has anyone ever bypassed Tengen's barrier?

Accepted Answer

Yes — multiple times. Toji Fushiguro bypassed the concealing barrier around the Tombs of the Star Corridor because his Heavenly Restriction stripped him of all cursed energy, giving the barrier nothing to detect. Hanami bypassed it during the Kyoto Goodwill Event because her cursed energy resembles a natural spirit rather than a standard curse. Mahito located the cursed warehouse by tracing the energy signature of a talisman. Tengen's barrier conceals — it does not reliably block determined opponents who operate outside normal cursed energy parameters.
