Isekai manhwa are known for their unique features. They are stunning with detailed battle scenes, close-ups, intricate animations, and many special effects. Thus, adapting these manhwa into anime can yield very different results. It could be a hit like Solo Leveling or A Returner’s Magic Should Be Special. Or, it could fail miserably.

The risk is high, and the rewards might not be as great as they seem. Here are five Isekai manhwa that might be too hard to adapt into anime. They range from a classic reincarnation story to a tale about a skeleton trapped in an infinite loop.

1. The Beginning After The End

Its Battle Scenes Might Be Impossible to Adapt With 100% Fidelity

• Genres: Action, Drama, Fantasy, Dark Fantasy, Sword And Sorcery, Isekai
• Author: TurtleMe
• Status: Hiatus (Until September 2024)

The Beginning After The End (TBATE) follows Arthur Leywin, a reincarnated monarch who was once King Gray in another world. Despite being the strongest, Arthur lived a lonely past life. Now reborn as the son of retired adventurers, he begins his journey in a new life full of mystery and power.

Challenges for Anime Adaptation:

TBATE’s fight scenes are complex and fluid, posing challenges for accurate animation. The series has intense battles, detailed creatures, and dynamic moments, especially highlighting Sylvie, the main character’s dragon. An anime that misses these elements might lose its appeal, as the fights and Arthur’s strength are key highlights.

2. I Reincarnated As An Evolving Space Monster

Gruesome Scenes and Legal Issues Might Be a Roadblock

• Genres: Sci-Fi, Action, Gore, Terror
• Author: FearTurtle (Gongpouigeobug-i)
• Status: Ongoing

This story is about a protagonist reincarnated as a monstrous space creature, similar to an Alien Xenomorph. It can evolve and cause chaos.

Challenges for Anime Adaptation:

The biggest problem lies in the gruesome scenes that are integral to the series. The gore and body horror would likely be toned down to meet broadcasting standards, which could upset fans. Also, its similarities to Ridley Scott’s Alien could cause legal issues. The manhwa does have unique aspects, like the monster’s voice mimicry.

3. The Extra’s Academy Survival Guide

Special Effects Could Break the Budget

• Genres: Action, Isekai, Sword & Sorcery, School Life, Shounen, Drama
• Authors: Corita (Story), Girin Geurin (Art)
• Status: Ongoing

In The Extra’s Academy Survival Guide, Ed Rothtaylor is reborn as a minor villain from a game. He uses his knowledge to avoid disasters, but this creates chaos, leading to greater dangers.

Challenges for Anime Adaptation:

The story’s combat scenes, featuring many summoned creatures and intense magic battles, could be very costly to animate. If the studio cuts back on visual quality, it risks losing the manhwa’s essence, leading to a disappointing adaptation.

4. The Magic Academy’s Genius Blinker

Flashy Abilities Could Cause Animation Headaches

• Genres: Action, Isekai, Fantasy, Sword & Sorcery, School Life, Shounen
• Authors: Eunmilhi (Story), Seoyu (Art)
• Status: Ongoing

Baek Yu-Seol, the protagonist, is reincarnated into a high-fantasy game. He is a weak character who specializes in the Blink spell, allowing him to move instantly across space.

Challenges for Anime Adaptation:

Animating the quick, Blink-based combat would be a challenge for studios. It involves fast movements and spellblade attacks. Simplifying these scenes might lead to a dull adaptation, losing the original’s visual appeal.

5. The Skeleton Soldier Failed To Defend The Dungeon

Animating A Skeleton Protagonist Is Much Harder Than It Seems

• Genres: Dark Fantasy, Drama, Isekai, Action, Adventure
• Authors: Sosori (Story), Ant Studio (Art)
• Status: Ongoing

This manhwa tells of a skeleton warrior who is reincarnated in an endless loop. He fights to protect his dungeon and uncover dark secrets.

Challenges for Anime Adaptation:

Animating a skeleton main character is tough. Most animated skeletons are often static, clunky, and brief. However, making a whole series with a skeleton in full-body fights, wearing armor and capes, is even harder. It demands a lot of resources. Without the right studio, the result could be stiff and awkward.

Conclusion:

Turning these Isekai manhwa into anime carries big risks, like high costs and legal issues. These stories are full of characters and detailed worlds, yet studios must make tough choices to keep quality and the manhwa’s charm. If done right, any could be the next big Isekai hit in anime.
