Solo Leveling Episode 21 Will Officially Start the Jeju Island Arc

Solo Leveling Episode 21 will be released on March 1st, and it is finally time for the most awaited arc, Jeju Island Arc is about to begin.

This will likely be the last arc of Season 2. A lot of fans and even some big media outlets thought A-1 Pictures would not be able to fully adapt Jeju Island in this season without compromising on the quality and the chapters, but they proved everyone wrong.

The latest episode already showed that with the fight between Baran and Sung Jinwoo, which was the best-animated fight so far.

While Season 1 covered only 45 chapters, Solo Leveling Season 2 has already adapted 43 chapters in just 8 episodes, and with 13 episodes in total, they are moving fast.

Some scenes were cut from the manhwa, but they don’t really affect the anime experience for those watching it for the first time.

The Jeju Island Arc is the longest arc so far, covering 18 webtoon chapters. Since 20 chapters will be adapted in the remaining 5 episodes, the pacing will be similar to what we have seen so far. Moreover, a major plot will be cut from the Jeju Island Arc as well.

The latest episode concluded the fight between Sung Jinwoo and Demon King Baran, adapting chapters 82-87.

Even though the arc is not fully done yet, it will finish in the next episode. That episode is important too because Jinwoo now has everything he needs to craft the Elixir of Life and finally cure his mom’s Eternal Sleep disease.

Major Spoilers From Solo Leveling Episode 21

Sung Jinwoo Will Receive the Demon Monarch Ring and the Purified Blood of the Demon King in Solo Leveling Episode 21

Solo Leveling Episode 21 will pick up right where the last episode ended. Sung Jinwoo has finally won his fight against Baran, clearing all 100 floors of the dungeon created by the system. Now, the Radiru Clan takes over as the rulers of the Demon Castle (yeah, not Radish, Radiru).

Jinwoo decided to clear this dungeon to get the Elixir of Life, an item that can cure any disease. In the Solo Leveling story, we only see it used to cure the Eternal Sleep disease, but it is supposed to be an all-healing item.

On his second trip to the Demon Castle, he got the first two ingredients after defeating Vulcan and Metus.

In Episode 21, he will finally get the last item, the Purified Blood of the Demon King. With this, he will be able to craft the elixir and finally cure his mom.

Jeju Island Raid Plan Will Be Discussed

In the latest episode of Solo Leveling, Goto Ryuji, Japan’s strongest hunter, has already made his appearance, and the Jeju Island raid plan is set.

The plan for the raid is, that Goto Ryuji’s squad will lure the ants out, while Korea’s S-Rank hunters will take care of the Ant Queen and her guards.

If the Ant Queen is killed, the problem will solve itself over time. The ants have a lifespan of only one year, and since the Queen is the only one who can reproduce, they will eventually die out.

Meanwhile, after Sung Jinwoo returns from the Demon Castle, he will finally cure his mother. Soon after, the Hunter Association Chairman will call him in to discuss Jeju Island.

When Jinwoo arrives at the association, he will instantly sense the powerful mana of all the S-Rank hunters sparring in the gym.

To test each other’s strength, the S-Rank hunters from Goto’s squad will go up against Korea’s S-Rank hunters in a sparring match. The upcoming Solo Leveling Episode 21 will most likely adapt Chapters 88, 89, 90, and 91. The official synopsis has been released as well:

After clearing the Demon’s Castle and obtaining the Elixir of Life, Sung Jinwoo heads to his mother’s hospital room, finally claiming his true reward. However, a lingering unease haunts him—has he stepped into a realm he was never meant to enter?

Meanwhile, Jinwoo is strongly urged to participate in the raid to reclaim Jeju Island. It’s a rare opportunity for significant level-up gains, yet in his mind, the images of his mother and sister, Jinah, continue to surface.
