Anime Solo Leveling part 2 has been released for 2 episodes and has changes compared to the original. So does that affect the main plot of the story, let's analyze with Hobiverse.
Anime Solo Leveling part 2 continues the journey of the fascinating character
After releasing an impressive trailer , Solo Leveling season 2 aired episode 1 on January 4, 2025, episode 2 on January 12, 2025. Season 2 marks a new turning point in Sung Jin-woo's upgrade journey, from an E-rank hunter (and once considered the weakest in the world) thanks to the mysterious system has become one of the strongest hunters. Mysterious gates that endanger the public continue to appear, Jin-woo will have to face many new challenges to protect everyone and himself.
Solo Leveling season 1 ended with Jin-woo having a new “job” - Necromancer. Not only did he continue to level up, but he also summoned a powerful army of shadows to serve him, including Igris - the most powerful S-class Knight Commander. Jin-woo now officially entered the ranks of the strongest and unknown hunters.
The first two episodes of season 2 are considered to maintain the spirit of season 1, with exciting battles and groundbreaking character journeys. However, the anime is significantly faster-paced than the manhwa, causing some scenes to not appear in the movie.
Solo Leveling part 2 shortens the plot to make the pace faster
The first season of the Solo Leveling anime adapted the 45 chapters of the manga, making it into 13 anime episodes and showing Jin-woo's entire initial journey. In the second season, the anime adapted more than 10 chapters in the first two episodes, which was considered quite fast and removed some scenes from the manhwa.

Some scenes that did not appear in the anime include:
-
The anime begins with a flashback to the events on Jeju Island (where there is an S-rank gate), while the manhwa introduces the event later. The scene reveals that monsters have appeared in the normal world and the other characters are conducting reconnaissance on the island.
-
Scene of Jin-woo opening an account at the bank
-
Scene where Hwang Dongsoo asks Woo Jinchul about the funeral of his brother Hwang Dongsuk, a low-level hunter who once confronted and was killed by Sung Jinwoo in a dungeon conflict.
-
Scene of Jin-woo performing his daily duties inside the dungeon
-
Jinho misunderstood Jin-woo's relationship with SongYi but in the anime there was no scene where Jin-won explained that she was just his sister's friend.
Aside from the Jeju Island incident, which has made manhwa fans worried about how it will affect Sung Jin-woo's character development, if the next episodes of the anime skip over the important battles, it will be hasty to convince about how Jinwoo reached level 100 and defeated the Ant King on Jeju Island. The remaining small details are omitted so as not to affect the flow of the show too much. Adjusting these scenes is to ensure the anime's pacing fits the time limit and focus on the main events to attract viewers.
Talking about how to build the main character Sung Jin-woo
In manhwa
Sung Jin-woo is shown to be a weak, timid person who often stands behind his teammates when killing monsters and is called the weakest hunter in the world, but he always tries to protect his family and teammates despite his limited abilities.

Through many times facing life and death, he became a cold, decisive person, with a high focus on the goal and a great sense of responsibility. Because the manhwa will have more room for drama, the story develops Jinwoo's personality slowly, helping readers deeply feel the change from "the weakest hunter" to "Dark Hunter".
In Anime
Jinwoo in the anime shows more intense emotions, especially in the early stages when his abilities are still weak. His personality is portrayed more simply, to suit the general audience.
Some of the cold and assertive aspects of the adult version are toned down and more emotional to make it more appealing to anime viewers. This makes sense, the characters' personalities are often more clearly built in manhwa than in anime, thanks to the more detail and development time. And in Solo Leveling, the fight scenes also seem to be a bit shorter than in the first season, but it has satisfied fans nonetheless.

The first two episodes of Solo Leveling season 2 have a score of over 9 with thousands of votes on IMDb. Solo Leveling is also ranked highest on MyAnimeList.
Let's wait with Hobiverse for episode 3 of Solo Leveling part 2, scheduled to be released on January 18, 2025.
