In Jujutsu Kaisen, the Shibuya Incident arc reaches a significant point during the Sukuna vs. Mahoraga fight, where Sukuna’s use of Reverse Cursed Technique projection becomes a focal point.
This arc reveals an intriguing aspect of Sukuna’s character: his ability to heal others using this technique, despite being notoriously selfish and vicious.
Reverse Cursed Technique projection was shown to be a powerful tool capable of destroying Curses with one shot, which Sukuna employed to save Megumi Fushiguro from Mahoraga. This situation has led to debate among fans regarding whether Sukuna’s use of this ability is a plot convenience or a reflection of his character traits.
The primary explanation for Sukuna’s knowledge of Reverse Cursed Technique projection is likely due to Gege Akutami’s narrative decision. Sukuna’s intention to eventually take over Megumi’s body makes it plausible that he would possess this ability to aid in his plan.
While Sukuna’s primary goal was to save Megumi for future possession, the Reverse Cursed Technique projection provided a practical means to do so, showcasing how he could use this technique to eliminate Curses effortlessly.
Sukuna’s disdain for Curses, as demonstrated during his encounters with characters like Mahito, supports the idea that he learned Reverse Cursed Technique projection to deal with Curses more effectively.
Given Sukuna’s status as the strongest sorcerer in history, it stands to reason that he would master techniques that enable him to eliminate obstacles, including Curses, with minimal effort.
Sukuna’s interest in Megumi Fushiguro also plays a significant role. Megumi, as a member of the Zen’in clan, has access to powerful Cursed Techniques, including the summoning of Shikigami.
Sukuna recognized the potential of these abilities and aimed to use Megumi as a vessel by having Yuji Itadori consume his fingers and eventually force Megumi to do the same. This plan culminated in Sukuna’s ability to defeat Satoru Gojo using Megumi’s body, with Shikigami like Mahoraga playing a crucial role in their battle.
Ultimately, Sukuna’s use of Reverse Cursed Technique projection in the series may be primarily a narrative choice by Akutami to facilitate the plot, allowing Sukuna to save Megumi for his own purposes. However, it also aligns with Sukuna’s character, reflecting his practical approach to defeating Curses and achieving his goals.
