Many questions remain unanswered in Solo Leveling, leaving fans with lingering curiosity about different aspects of the story. While the series provides thrilling battles, well-developed characters, and an intense power system, certain mysteries remain unresolved.
Some of these questions revolve around the true nature of the System, the origins of the Monarchs, and what could have happened if events played out differently. The story introduces powerful beings and forces beyond human understanding, yet not all of their motives are fully explained.

Readers are left to wonder about the true limits of Sung Jin-Woo’s abilities and whether there are threats beyond what was revealed. Even after the final battle, some aspects of the story feel incomplete, as if there is more to be explored.
These mysteries continue to fuel discussions, with many theories emerging about what could have happened or what was left untold.
The True Origin of the System
One of the biggest questions concerns the System itself. While it is presented as a tool to help Sung Jin-Woo grow stronger, its deeper origins are never fully explained. It is known that Ashborn, the former Shadow Monarch, created it as a means of selecting his successor.
However, many details about how it functions and its exact limitations remain unknown. Did Ashborn design it alone, or was there another force involved in its creation? The way the System interacts with reality also raises questions.
Unlike normal magic, it has the ability to rewrite history, manipulate time, and defy the natural laws of the world. Even its ability to grant Jin-Woo limitless growth suggests it is far beyond human technology or magic.
The way the System communicates also hints at something more complex. It operates like an artificial intelligence, sending messages and guiding Jin-Woo’s decisions. While it seems to have some level of autonomy, it never acts against Jin-Woo’s interests.
Could it have developed its own will, or was it strictly following Ashborn’s original programming? Another mystery is whether the System could have been given to someone else.
If another hunter had been chosen instead of Jin-Woo, would they have received the same powers, or was there something unique about him? These questions leave much to be explored about the true extent of the System’s influence.
The Unknown Future of the Monarchs and Rulers
While the war between the Monarchs and the Rulers plays a central role in the story, not everything about these powerful beings is revealed. The Rulers are introduced as beings who seek to maintain balance, while the Monarchs desire destruction. However, their full history and motivations remain unclear.
How did the war between these two factions begin, and was there ever a time when they coexisted peacefully? The story suggests that the Rulers were once human-like beings who ascended to higher forms of existence, but the exact process behind this is never shown.

Similarly, the origins of the Monarchs are shrouded in mystery. Were they always enemies of the Rulers, or was there a time when they were part of the same force?
Another major question is whether new Monarchs or Rulers could emerge in the future. With Ashborn passing his power to Jin-Woo and the other Monarchs being defeated, it might seem like their war has ended. However, powerful forces rarely disappear completely.
If new beings were to rise, would they follow the same path as their predecessors, or would they seek a different kind of balance? The possibility of an even greater enemy existing beyond the known Monarchs and Rulers is another unanswered mystery.
The story does not confirm whether all threats have been eliminated, leaving room for speculation about what could come next.
Other Mysteries That Remain
Many smaller details throughout the series also raise questions. The dungeon breaks that initially threatened humanity seemed to be connected to the war between the Monarchs and the Rulers, but their true source was never fully explained.
If the Monarchs were gone, would dungeon gates still appear, or had they been permanently erased? Another question is whether Sung Jin-Woo’s power has any limits. Even without the System guiding him, he continued to grow stronger. If he kept training, could he surpass even the original Shadow Monarch?
There is also the matter of other dimensions. The story suggests that there are realms beyond what humans can see, but little is revealed about them. If Jin-Woo had traveled to these places, what could he have discovered? Could there be beings even stronger than the Monarchs hidden somewhere?
These unanswered questions keep the story alive long after its conclusion, leaving room for speculation about what might have happened beyond what was shown.
