WARNING: Spoilers for the Jujutsu Kaisen manga!!

Jujutsu Kaisenhas consistently been a series that follows its own set of rules, especially when it comes to domains and cursed techniques. However, a common complaint among fans is that Megumi Fushiguro seemingly survived an impossible situation, being hit by Unlimited Void five times, without suffering permanent brain damage. Many claim this is an example of plot armor, but a closer look at the mechanics of domains proves otherwise.

Megumi’s survival is not due to the story taking it easy on him; rather,it is because of how Unlimited Void interacts with his soul rather than his physical body.By breaking down how domains work and what happened in his battle against Gojo, it becomes clear that Megumi’s endurance is not a narrative shortcut but alogical consequence of the rulesJujutsu Kaisenhas established.

The Truth Behind Megumi’s Survival

Why Megumi Did Not Die or Become Incapacitated

At first glance, it might seem absurd that Megumi could withstand five instances of Unlimited Void when a single exposure is enough to incapacitate most sorcerers. However, the key detail is that Unlimited Void primarily affects the soul rather than the physical brain. This distinction is crucial in understanding why Megumi’s condition, though dire, was not terminal.

A crossover fans never expected has occured when BTS member Kim Namjoon posted on his Instagram story about Nanami from Jujutsu Kaisen.

After the battle, Megumi himself stated that he felt dizzy,indicating that his soul had been affected rather than his physical body.Unlike typical domain effects that require a tangible target, Unlimited Void bombards the soul with an overwhelming amount of information. This means that while Megumi’s soul took significant damage, his brain wasn’t subjected to the same destruction as a regular victim would experience.

Additionally, at the time, Megumi was not even physically present in the traditional sense.Because he was under Sukuna’s possession, his physical form was more of a vessel than an independent body, which meant that Unlimited Void’s effects were limited to his soul.This nuanced difference is what allowed Megumi to remain functional, though severely weakened, rather than completely brain-dead.

How Domains Work in This Context

Why Sukuna’s Protection Did Not Extend to Megumi

To fullyunderstand why Megumi was not completely destroyedby Unlimited Void, it is important to understand how domains function inJujutsu Kaisen. Domains have specific activation conditions and effects, and they do not all operate under the same principles. Sukuna’s Malevolent Shrine, for example, functions differently from Gojo’s Unlimited Void in ways that are crucial to Megumi’s survival.

Sukuna’s domain protected his own body and soul from the effects of Unlimited Void. However, since Megumi was merely a host, Sukuna’s protection did not extend to him. This meant that while Sukuna could endure the effects of Gojo’s technique, Megumi’s soul was left vulnerable.

Since Megumi’s body was not physically present in a way that could be directly attacked, Malevolent Shrine had no effect on him.

Meanwhile, Malevolent Shrine operates on an open-barrier principle that allows it to target physical objects within its range. Since Megumi’s body was not physically present in a way that could be directly attacked, Malevolent Shrine had no effect on him. This is why Sukuna remained unharmed, while Megumi only suffered damage to his soul from Unlimited Void instead of being physically cut apart.

The Role of Unlimited Void in Attacking the Soul

Why Unlimited Void Did Not Destroy Megumi’s Brain

Unlimited Void is unique because, unlike most domains, it doesn’t require a physical target. Instead, it overwhelms an opponent’s mind by flooding them with infinite knowledge, effectively paralyzing them.The key factor in Megumi’s survivalis that while his soul was directly exposed to this onslaught, his physical brain wasn’t actively being destroyed.

Mahito’s domain, Self-Embodiment of Perfection, operates on a similar principle, directly affecting the soul rather than the body.Since Gojo’s technique works in a comparable way, its impact on Megumi was significant but not necessarily fatal.The damage inflicted was severe, but because Megumi’s body wasn’t fully “present” in the same way it would be under normal circumstances, he avoided irreversible consequences.

This explanationaligns with established lore inJujutsu Kaisenrather than contradicting it. If the series had disregarded its own mechanics to keep Megumi alive, it would indeed be an example of plot armor. However, the fact that the series adheres to its own internal logic proves that Megumi’s survival is a consequence of the rules rather than an exception to them.

The argument that Megumi survived five instances of Unlimited Void due to plot armor falls apart when examining the mechanics of domains and how they interact with souls versus physical bodies. His endurance is not a cheap narrative trick but a logical outcome of the way Sukuna’s possession, Malevolent Shrine’s limitations, and Unlimited Void’s unique effects all intersected.​​​​​​​

Jujutsu Kaisenhas consistently adhered to its established rules, and Megumi’s situation is no different. While his soul took significant damage, his physical brain was never at risk, which explains why he remained functional, albeit severely weakened, after the fight. Far from being an instance of plot armor, his survival is a testament to how well-thought-out the series’ power system truly is.
