While Solo Leveling's anime is known for its intense action and incredible animation, following Jinwoo's power trip, there are quite a few secrets hidden that continue to captivate fans in the story. From the first episode, Solo Leveling has introduced an intriguing world where even the most experienced hunters don't know much about what's behind the doors. However, instead of revealing some of these mysteries in the first two installments of the series, viewers' questions have only increased after Solo Leveling Season 2's finale.

Unfortunately, even though, due to its enormous popularity, the future of the franchise seems bright, given that Solo Leveling Season 3 has not yet been confirmed, these mysteries are still up in the air, keeping fans anticipating when they will be answered. While the most impatient fans may have already consulted the source material to find out how the story continues, those waiting to see it animated are in for a treat, as there are a lot of Solo Leveling's mysteries to uncover once the anime returns.

10 The Purpose Behind the Gates Appearing in the World

The Gates Might Bring Greater Dangers in Solo Leveling Season 3

At the beginning of the series, it is explained that gates spontaneously started to appear in the world, and people began awakening powers that allowed them to fight the beasts coming from them, becoming hunters. While this affected the balance of the world, creating an organization to regulate these hunters, multiple guilds and side jobs meant to the areas involved in this line of work, as well as commercializing resources from the dungeons, the gates continued to be an unpredictable variant that puts humanity in danger.

The gates are unnatural to the world despite a good percentage of the population being able to use mana, since there are people that fall sick with the Eternal Slumber because of them, like Jinwoo’s mother and, most recently, Jinho’s father. The fact that in Solo Leveling season 2's finale there were creatures able to open gates as well as the system sending Jinwoo through them points out that these portals might have been created by someone and be part of a larger-scale conflict that will inevitably pose a risk to the world.

9 The Identity of Igris’ Original Master

The Red-Blood Commander Was Waiting for Someone

In the Job Change arc in Solo Leveling Season 1, episode 11, the quest that Jinwoo had to overcome was defeating the Red-Blood Commander Igris, who was standing guard over an empty throne. Igris was really strong, and Jinwoo was only capable of winning because of his willpower pushing him to sur his limits. Yet, there's still not much information about who Igris was waiting for.

Are you waiting for your king to return? The king who may not return at all. Commander Igris. You are a warrior. Wielding your sword against enemies must be your inner desire. Do you want to let your sword rot in such a desolate place? If you need someone to wield your sword for, fight for me. Don't guard that empty throne. Protect me, who stands before you. - Sung Jinwoo

When trying to use shadow extraction on Igris, Jinwoo failed two attempts before due to the difference in power levels. However, Jinwoo opted for another strategy, convincing Igris to serve him instead of waiting for a king who may not return. The focus of Igris’s status as a powerful commander, as well as Jinwoo becoming his new master, highlights that it is only a matter of time before viewers find out who was Igris’ original master.

8 The Ancient War of the Demon Clans

Esil and the Radiru Clan Were Sent to the Demon Castle

The Return to the Demon Castle Arc sparks many questions from viewers as, when questioned by Jinwoo, Esil Radiru reveals the demon clans were originally in the Demon World but were sent away to fight in a war against a powerful enemy. However, before she could reveal who they were fighting, Esil was blocked by the system, stating it was too soon for Jinwoo to hear this information.

In Solo Leveling Season 2, episode 9, after Jinwoo defeats Baran and leaves the gate, its shown a system notification stating that the Demon Castle "will return to its original state."

It's still uncertain for anime viewers who are behind this conflict, but it's evident that it relates to Jinwoo, especially since in the Demon Castle he meets for the first time another monarch, Baran, the monarch of the White Flames. Although nothing was further disclosed in their fight, the king of demons, could be the key to the nature of Jinwoo's power and the truth about that ancient war.

7 The Origin of the National Level Hunters

There’s a Striking Difference Between a Regular S-Rank and a National-Level Hunter

Solo Leveling Season 2 has overlooked several scenes meant to build up the National Level Hunters, like shortening Thomas Andre’s introduction in episode 9 without delving into what a force they represent for a nation. However, the appearance of Liu Zhigang in the season finale, casually destroying a swarm of flying ants arriving at the coast of China, highlights how they are on a whole different level from the regular S-Rank hunters who struggled with them earlier in the arc.

The National Level hunters are still a mystery in Solo Leveling's anime, as well as how many of them there are and which country they belong to. Moreover, it is still to be seen if Jinwoo is on par with them or if he still has to keep leveling up some more before facing them. However, the biggest mystery is the reason behind such a monstrous strength without being related to a system like Jinwoo, sparking questioning about what makes them so different from the rest of the S-Rank hunters.

6 Jinwoo’s Conflict with His Humanity

Jinwoo’s Change After the Double Dungeon Might Hide a Deeper Meaning

Although this has been toned down in the anime by cutting Jinwoo’s morally gray moments, one of the most interesting aspects of his character is his loss of humanity. The ethical dilemmas that come along with power are first highlighted in Solo Leveling episode 9, where Sung Jinwoo notices that his emotions and humanity are fading as his strength increases. This could not have a deeper meaning beyond highlighting Jinwoo’s trauma in the double dungeon and making him cold-hearted and desensitized to violence to not doubt when it comes to turning humans into shadows, like with Kim Chul in the Red Gate.

“I Feel Like Something Within Me Is Lost Every Time I Get Stronger” - Sung Jinwoo, Solo Leveling Episode 9

However, Jinwoo’s radical change might tide with the fundamental part of his powers as a necromancer. Jinwoo's class is based on darkness as the Shadow Monarch and there might be something glazing at him from the abyss, just like was pointed out by Kang Taeshik. Whether this will be explored in-depth or if Jinwoo might let himself be consumed by the darkness would be an interesting aspect to look forward to in Solo Leveling Season 3.

5 The Election of Jinwoo As a Player

Is Jinwoo the Only Player of the System?

The first mystery that opens the story is Jinwoo being saved by a mysterious game-like system to be a player when he was on the brink of death inside the Double Dungeon in Solo Leveling Season 1, episode 2. However, besides some small hints, there hasn’t been much revealed about it since then. There are many questions surrounding the system in general and for what purpose Jinwoo was chosen as a player, as well as if there are any others besides him that have yet to be introduced in the series.

Viewers know that someone is controlling Jinwoo’s growth, as the fact that every one of his quests makes him stronger proves that, pointing at a larger conspiracy building up in the shadows. However, beyond the title of the series, the reason why he is the only player in the story is one of the biggest mysteries that Jinwoo might unveil once he finds more clues about who created the system.

4 The Glitches of the System

The Magic Beasts Are Being Controlled To Not Disclose Information Ahead of Time

One of the biggest questions of the viewers through Solo Leveling Season 2 is the glitches that appear every time that the magic beasts are about to reveal something related to the nature of the gates and Jinwoo’s powers. The first time this happened was in Solo Leveling Season 2, Episode 2, when Baruka was talking about how the magic beasts hear a voice that influences them to kill humans and how Jinwoo was different to the rest.

The glitches appear later too, when Karlgalgan is shocked by Jinwoo’s power to awaken the death soldiers, and once again when he questions Esil about the clans in the Demon Castle. This last interaction is the one that gives more information, as it reveals that someone is controlling the magic beast and demon clans, but it is too early for Jinwoo to know about it.

3 The Identity of the Mysterious Beings on Jeju Island

These Powerful Enemies Have Been Lurking on the Sidelines

The aftermath of the Jeju Island raid revealed two mysterious beings that came from the gates, something never seen before in the story so far. The beast-like creatures can not only communicate, but they also seem to have immense power, being able to knock out several hunters with a forced barrier and opening gates to disappear without being noticed.

These beings were tracking the source of a great power, which was most likely Jinwoo, and they seemed to be following a meticulous plan that withheld them to act before the right time arrived. What is certain is that they pose a real threat to the and a new stage where beasts might attack outside the gates even without a dungeon break.

2 The Truth Behind the Disappearance and Return of Jinwoo's Father

Why Hasn’t Sung II-Hwan Returned With His Family?

Close

It was revealed in Solo Leveling Season 2 that Jinwoo's father, Sung II-Hwan, was able to survive inside a gate for a decade, returning with incredible strength, being able to overpower an S-rank Hunter. Likewise, even though he was accused of being a magic beast in human form, Il-Hwan tried to warn about a danger to the world in episode 4 of Solo Leveling Season 2.

Nothing more was revealed about Il-Hwan until his short appeared in the aftermath of the Jeju raid, where it's hinted that he is connected somehow with the mysterious beings, as he was keeping close surveillance on them. This confirmed he is currently involved in a greater conflict that has prevented him from returning to his family and that the circumstances related to Sung Il-Hwan's disappearance will most likely be revealed once these enemies start to execute their plans in an season.

It is obvious to viewers that someone is pulling along the strings of the System, who has been steadily leading Jinwoo to become stronger. From the daily quest to strengthen his body to the demon castle's instant dungeon that suspiciously has as a reward, the one thing that Jinwoo wanted the most to cure his mother, as well as using glitches to block him from hearing important information, these events relate more to an intricate conspiracy than a common plot armor device.

Furthermore, the system had foremost strived to preserve Jinwoo’s life when he was in mortal danger by activating an emergency quest, forcing him to kill the Lizard hunters and Kang Taeshik. As an Solo Leveling Season 2's finale brought again a key to unveiling the secrets of the system, Jinwoo is close to finding the identity of its creator.
