➠ Chapter 257 and Rebirth:

This chapter officially introduced the concept of Rebirth (환생, in which the actions of a sentient being lead to a new existence after death) into the plot of the manga. We can say it has been hinted at before through Jogo and Yuuji’s words for example, but the Rebirth of the soul of Sukuna’s twin officially confirmed it. We do not know the conditions of Rebirth in the world of JJK yet, but it implies the existence of Samsāra (윤회전생) which is the endless cycle of birth, death and rebirth, and it made me think of this illustration:

This illustration is based on the Kalachakra Mandala, which represents the wheel of our lives, and the time we have in this world to make peace with ourselves and achieve Enlightement (freedom from Samsāra). Kalachakra literally translates to ‘cycle of time’ (Kala meaning ‘time’ and Chakra meaning ‘cycle’). It means that everything in nature happens in the ‘cycle of time’.

These four characters being the centre of the above-indicated illustration is not random. Each one of them is in some way bound by the concept of Rebirth (Reincarnation). Chapter 257 gave us a good perspective on how Yuuji, Sukuna and Kenjaku are bound to it (and each other as well), which, considering the ties of the other three, may make it seem like Gojo is out of the equation.

Personally, there could be two interpretations of why Gojo is part of it (besides the simplest explanation that these four are central to the storyline):

1. As Tengen has implied themself before, Tengen, the Star Plasma Vessel, and the Six Eyes are all connected by fate. Through Tengen, we also learn that Kenjaku lost twice to a sorcerer with the Six Eyes, and after the second time taking no chances killed both the Star Plasma Vessel and the Six Eyes less than a month after they were born. We know that there has been a connection between Tengen, Kenjaku and the Six Eyes throughout time. Gojo could be part of the illustration to indicate the recurring existence of the Six Eyes, bound to Tengen’s existence whose relationship with Kenjaku we do not clearly understand yet, but has been as continuous.

Or

2. Drawing on the confirmation that the concept of Rebirth exists in the world of JJK, Gojo being part of this illustration could imply that perhaps the soul of Sukuna’s twin is not the only character who has been Reborn (note: we do not know yet whether Itadori Jin was his twin’s first reincarnation or he died and was reborn multiple times before (however, the way Sukuna says it implies the latter)). We do not know yet what the conditions for Rebirth are (or if they are the same as in Buddhism) or whether the Reborn soul retains anything of their past life, so it is difficult to make the assumption, but it opens up the possibility of Gojo being reincarnation as well, i.e. the Six Eyes are the same soul.

Regardless, the existence of the concept of Rebirth has opened many different (and interesting) possibilities.
