13 Isekai Anime with Non-Human Protagonists / MCs

The isekai genre is famous for transporting characters to fantasy worlds filled with magic, monsters, and unexpected adventures. However, some series go beyond the traditional formula by featuring protagonists who are no longer human (or weren't born as one), taking on forms such as monsters, skeletons, swords, and even unusual objects.

If you enjoy unconventional isekai with monster protagonists or uncommon creatures, this list is perfect for your next marathon.

Behemoth's Pet: The Elf-Girl's Cat is Secretly an S-Ranked Monster!

In this curious story, the protagonist is reborn as a seemingly cute kitten that actually belongs to a powerful monster species known as a Behemoth. After being adopted by an elven adventurer, he lives a life balanced between peaceful moments and intense battles.

The anime blends comedy, fantasy, and action, exploring the contrast between his adorable appearance and the fact that he is an extremely powerful creature.

The Unwanted Undead Adventurer

Rentt Faina was an ordinary adventurer until he was defeated by a dragon and reborn as a skeletal undead. From that point on, he embarks on a journey to evolve his monstrous form and perhaps regain his humanity.

The main appeal of the series lies in following this gradual evolution, showing how Rentt adapts to his new condition while continuing to pursue his dreams of being an adventurer.

Re:Monster

After dying, the protagonist reincarnates as a goblin, one of the weakest creatures in a fantasy world. However, thanks to a special ability that allows him to absorb powers by devouring enemies, he quickly evolves into increasingly powerful forms.

The series features fast paced progression, with the protagonist transforming from a simple monster into a feared creature.

Skeleton Knight in Another World

A gamer wakes up in another world trapped in the body of his game avatar: a skeleton knight. Despite his intimidating appearance, Arc maintains a kind personality and ends up using his massive power to help people in danger.

This series offers action, adventure, and humor, featuring grand battles and a protagonist who stands out for being quite literally a skeleton walking around in armor.

Reincarnated as a Dragon Hatchling

The protagonist reincarnates as a dragon hatchling in a fantasy world. Starting out extremely vulnerable, he must fight to survive while evolving and discovering the powers of his species.

The story combines survival and progression, following his transformation from a helpless creature into an imposing dragon.

Tonari no Yokai-san

The story follows a small village where humans and yokai coexist naturally. Among the central characters is a cat that, over time, transforms into a nekomata, a supernatural creature from Japanese folklore.

While not a traditional isekai, the series explores the lives of non human beings in a sensitive way. The focus remains on the relationships between the creatures and the residents.

Dog & Scissors

Harumi Kazuhito is a young man obsessed with books who ends up dying during a robbery. Since he still had so much left to read, he reincarnates as a dog and begins living alongside an eccentric novelist.

Dog & Scissors mixes absurd comedy and surreal situations. The protagonist, now trapped in a dog's body, must adapt to a totally different life while trying to understand the strange owner who took him in.

Reborn as a Vending Machine, I Now Wander the Dungeon

One of the most unusual concepts in isekai: the protagonist is reborn as an automatic vending machine. Even though he cannot move on his own, he utilizes his special functions to help people and survive in a world full of monsters.

The anime surprises by turning an absurd idea into something entertaining.

Butareba: The Story of a Man Turned into a Pig

After passing out while eating raw pig liver, the protagonist wakes up in another world in the body of a pig. There, he meets a girl with special powers and embarks on an unexpected journey.

The anime combines humor and fantasy but also surprises with darker moments. The idea of a hero trapped in the body of a seemingly defenseless animal makes the work very interesting.

So I'm a Spider, So What?

A student dies along with her class and reincarnates in another world as a small spider in a deadly dungeon. Alone and surrounded by monsters, she must use her intelligence and creativity to survive.

The protagonist wins over the audience with her fun personality and the way she faces impossible challenges. Her evolution from a fragile spider to an incredibly powerful creature is the major highlight here.

That Time I Got Reincarnated as a Slime

After dying, Satoru Mikami is reborn in a fantasy world as a slime. What seemed like a weak form quickly proves to be an advantage, as he acquires unique skills and becomes the powerful Rimuru Tempest.

The anime is one of the genre's biggest hits, combining action, politics, and humor. Rimuru proves that even a simple creature can become one of the most powerful beings in an entire universe.

Reincarnated as a Sword

In this one, the protagonist reincarnates as a sentient magical sword. Instead of fighting directly, he forms a partnership with Fran, a young warrior, and together they face monsters and dangers in a fantasy world.

The work stands out for the relationship between the two characters. The sword acts as a mentor and weapon, creating a different and charismatic dynamic.

My Life After Waking Up as a Dummy Head Microphone

This work takes the non human protagonist concept to the extreme: the character wakes up as a dummy head microphone used in binaural recordings. The premise is entirely unique and aimed at a comedic and experimental experience.

Although it is a short and quite peculiar series, it shows how an anime can explore absurd ideas in a fun way. It is an interesting curiosity for those looking for something completely outside the box.

For those who want to explore more eccentric works, this list provides options that will certainly surprise you. Which one is your favorite?
