The second season of Jujutsu Kaisen introduces us to young Gojo and Geto while opening a whole new jar of mysteries. One such mystery that will be introduced in the first episode is the concept of a star plasma vessel in Jujutsu Kaisen. It is related to Master Tengen, which anime viewers must have heard about in the first season. So today I've come up with an explainer to clear all the air regarding the star plasma vessel and its relationship with Master Tengen. Read on to learn more about the world of Jujutsu wizardry and why star plasma vessels are important.

Spoiler alert: This article contains spoilers for the story of Jujutsu Kaisen Season 2. We suggest you watch the anime and read the manga to avoid spoiling the intended experience.

Before we learn about the Star Plasma Vessel, you need to know about the Master Tengen and their role in the Jujutsu Society. So, Master Tengen is a Jujustu Sorcerer. Tengen's current form (or gender) is unknown but used to be a female human in the past.

What is so special about this character? Well, it's their innate Jujutsu technique, which is "immortality." This allowed them to live on forever, but there is a problem that comes with it, which is connected to the star plasma vessel.
