Mahoraga, one of the most formidable shikigami in Jujutsu Kaisen, is said to be one of the strongest, if not the strongest, entity summoned through the Ten Shadows curse technique used by Fushiguro Megumi in the series.
During the tense Shibuya arc, Megumi summoned Mahoraga when his own injuries left him unable to face Shigemo. However, Mahoraga's unruly nature was revealed immediately, as even Megumi was unable to control him and was quickly pushed aside when Mahoraga arrived.
The unique aspect of Mahoraga lies in its history; No witch throughout time has been able to completely tame this entity to their will, a feat that Megumi was also unable to achieve.
Megumi's growth in Jujutsu Kaisen
The inclusion of Mahoraga in the plot seems like a plot device to enhance Megumi's abilities and move the story forward. It is speculated that Sukuna's deep interest in Megumi's body as a vessel may partly stem from Mahoraga's potential, which further increases Megumi's importance in the series.
It's worth noting that Mahoraga's abilities play a key role in key battles, especially adapting Gojo Satoru's Infinity technique in one of the series' most epic matches.
Fans have debated the addition of Mahoraga to Megumi's list of shikigami, noting that it stands out due to its humanoid appearance, unlike the animalistic appearance of Megumi's other spirits.
Furthermore, Mahoraga's power level is far superior to that of the other shadows, which has led some to suggest that its inclusion was a deliberate move to elevate Megumi to the status of a top protagonist alongside Itadori Yuji and Kugisaki Nobara.
Despite the perceived inconsistency, Mahoraga's pivotal role in key battles emphasizes its importance in the plot rather than just serving as a storytelling device.
