Summary

• The Solo Leveling anime successfully adapts the manhwa and light novel without any noticeable negative impacts, condensing and contextualizing content to fit the animated style of storytelling.
• The anime introduces minor changes to certain scenes and characters, such as removing a scene where Sung Jinwoo asks for coffee and changing the character who opens the doors to the double dungeon.
• The anime includes early appearances of significant characters, such as President Go Gunhee, to provide hints of the deeper political tides that will be explored in the future.

The biggest differences between Solo Leveling’s anime and the manhwa are subtle but have tangible effects on the portrayal of the story in its new medium. Just the first episode alone exhibits at least ten alterations, additions, or cuts that did not occur in the manhwa, including details ranging from minor incongruencies to the creation of completely new content in of story structure.

Despite all the changes, the Solo Leveling anime lives up to high expectations, as none of the differences have any noticeable negative impacts. This is quite an achievement, considering the difficulty of adapting a manhwa that is already an adaptation of a light novel. The anime needs to condense and contextualize any content available to fit the animated style of storytelling, whether that is utilizing scenes present in the light novel but not the manhwa, or scenes that had never existed altogether, and A-1 Pictures does an excellent job.

15 Jinwoo Talks to Jinah About the Raid

The incident in the C-rank dungeon where Jinwoo is forced to kill Hwang Dongsuk and his entire raid party is quite a pivotal moment for Jinwoo's character and the anime stresses the brevity of the event with a genius scene added to episode #7 of the anime. In the manhwa, Jinwoo is seen simply eating and drinking with Jinah in their apartment with little conversation between the two. Jinah simply asks whether Jinwoo is in a good mood as he is treating her to chicken wings and the chapter then cuts directly to Jinwoo discovering his inability to get drunk.

However, in the anime, Jinah asks Jinwoo about his most recent raid which forces him to reflect on the events of the raid and his irreversible actions. The scene helps better flesh out Jinwoo's character arc and confirms just how much the System has changed Jinwoo in a short span of time.

14 Kim Sangshik's Death Was Cut Short

Another subtle difference between the manhwa and the anime can be noted in episode #9 when Kim Sangshik, one of the few survivors of the Double Dungeon, is attacked by Kang Taeshik. In the manhwa, Sangshik is shown ing various conversations with his wife and children about why he became a hunter and him promising to return to his family who very much needs him. This flood of memories ends with Sangshik desperately wanting to live and survive when Jinwoo and the rest find him.

In contrast, in the anime, Jinwoo and his group directly discover the gravely injured Sangshik, who then apologizes to Jinwoo and dies after Joohee's efforts to help him prove to be fruitless. Instead of showing Sangshik's thoughts right at that moment, the anime includes a brief scene of Sangshik with his family in the episode preceding the raid. Though he may be a minor character, Sangshik's death in the manhwa was much more dramatic and impactful as a result of this little glimpse into his character at the right moment.

13 The Hunters Guild Sets Out on an Expedition to Scout Jeju

One of the biggest changes made to the anime takes place in the very last episode which shows the Hunters Guild setting out to scout the situation at Jeju while preparing for the next raid. While on the way to Jeju, the hunters spot one of the newly evolved monster ants in the sea, which they then bring aboard. The hunters discover the ants have developed wings well in advance as compared to the manhwa and expedite the planning for the Jeju Island Raid.

That said, in the manhwa, the hunters do not find out that the ants have evolved until well after one attacks an island on the coast of Japan which causes many casualties. The Korean Hunters Association then plots a plan of action along with the Japanese hunters. Evidently, this change was made in an effort to set up the Jeju Island Raid well in advance given the excitement surrounding the arc.

12 Jinwoo Drinks Kasaka's Venom Against Cerberus

One of the most noticeable changes made in the anime adaptation of Solo Leveling was Jinwoo's fight against Cerberus, which was made much more dynamic than the manhwa. In the anime, Jinwoo suddenly re he still has Kasaka's venom and uses it at the very last moment to give him an extra boost to beat the three-headed guardian. The venom lowers physical damage taken by 20% in exchange for reducing Jinwoo's strength by 35% and plays quite a crucial role in the battle.

However, in the manhwa, the venom is nowhere to be seen in the battle against Cerberus. Jinwoo drinks the venom immediately after discovering his immunity to poison while drinking alcohol at home with Jinah. Jinwoo tests out the venom but discovers that the automatic detoxification also takes away any buffs provided by the venom almost instantly rendering the venom all but useless.

11 Joohee Gets a Call From Her Parents

In the larger scheme of things, Joohee, the B-rank healer who befriends Jinwoo early on, remains quite a minor character. However, the anime doesn't miss the chance to develop her character and the world of Solo Leveling through her. A short anime-only scene in episode #8 shows Joohee's mother checking up on her over the phone. Joohee's mother appears visibly concerned about her and recommends she quit being a hunter and come help with her family's business instead.

Joohee, who at this point is still struggling with the trauma from the Double Dungeon, is forced to acknowledge her abilities and decides not to give up. At that very moment, Joohee receives a request to participate in a D-rank raid where she reunites with Jinwoo. Despite being relatively short, the scene highlights the darker side of hunter society where many like Joohee are often left with permanent mental scars, even if they may not be weak E-rank hunters.

10 Jinwoo Doesn’t Try To Get Coffee

After the prologue of Solo Leveling’s first episode, main character Sung Jinwoo is introduced, as a team of low level hunters prepare to enter a dungeon at a construction site. Everything in the scene is quite similar to the manhwa, but there is a slight difference in the way Sung Jinwoo makes his entrance.

In the manhwa, he asks the vendor for a cup of coffee, but they run out right before Jinwoo gets there, giving the sense that Jinwoo is an insignificant and neglected part of the greater hunter collective. The anime decides to leave this subtly pitiful scene out, and Jinwoo only casually greets hunter Kim Sangshik, who was able to get a cup.

9 Kim Sangshik Opens the Doors to the Double Dungeon

In the rising action of Solo Leveling’s first episode, Sung Jinwoo’s group of hunters encounters an anomaly in the originally D-ranked dungeon they entered. A long tunnel leads to a separate room, a phenomenon called the double dungeon, which is incredibly rare. The group of 13 (17 in the manhwa) are torn about whether they should enter or not, and they eventually take a vote that narrowly wins in favor of entering thanks to Jinwoo serving as the deciding factor.

This situation is consistent between the anime and manhwa, but there is a slight deviation between who gives the group the final push to enter the doors. In the manhwa, it is team leader Song who pushes open the doors, but in the anime, it is Kim Sangshik. Although this is a slight variation, it will be interesting to consider how this change will affect the respective guilt that was present in both Song and Kim later in the manhwa, and how it will carry over to the anime.

8 President Go Gunhee Makes an Early Appearance

The first episode of Solo Leveling is chock-full of spicy details that fans of the manhwa and light novel will catch on to. The anime is structured knowing that fans will recognize early character appearances and won’t be as confused as if the manhwa made so many early character introductions.

One such character who makes an early appearance is president Go Gunhee of the Korean Hunters Association, Korea’s equivalent of a governing body for hunters. However, compared to modern-day governments, the association holds relatively less power. Despite this, Go Gunhee is still an S-ranked hunter who is one of the strongest characters in the manhwa. His appearance in the anime’s first episode not only reminds fans of this legendary figure, but it also gives a hint to the deeper political tides that the series will experience in the future.

7 Sung Jinwoo Is Stabbed By a Goblin

Both the Solo Leveling manhwa and the anime do a great job in establishing Sung Jinwoo’s originally weak position as a hunter, especially in the descriptions of Jinwoo as the weakest E-rank hunter underdog. On this front, the anime takes it to the next level, adding visceral combat details within the first dungeon that Jinwoo is seen entering.

In the manhwa, the fight scenes against goblins are quick and flashy cuts, which are used to contrast the strength between the other D-rank and C-rank hunters against Jinwoo, who can defeat one goblin and gain its essence stone while sustaining some injuries. However, in the anime, after this victory, Jinwoo is ambushed by another goblin and stabbed in the stomach, leading to a frightening injury that had a large pool of blood spread from Jinwoo’s body. This is a completely new scene that even further exaggerates Jinwoo’s weakness.

6 Jinwoo’s Choice of Weapon Changes

In the Solo Leveling universe, because hunters’ strengths are set as constant following their awakening, weapons become ever so important. The same can be said for Sung Jinwoo, who is seen in the anime entering the dungeon at the construction site holding a knife. Then later, when he fights against goblins, the knife snaps, putting him in a perilous situation where he is stabbed.

As described earlier, this second goblin confrontation is a fresh scene in the anime, but there is still an additional difference. In the manhwa, Sung Jinwoo does not enter this dungeon with a weapon. In a flashback that he had in chapter 4 of the manhwa after he enters the same dungeon, Jinwoo mentions that he no longer goes hunting armed because the weapons he can afford easily break, and his profits don’t outweigh the costs. This puts further emphasis on Jinwoo's desperate struggle as a hunter to gain money for his mother's cures.
