What are some isekai novels or manga where the main character isn't human?

One great light novel with a non - human main character is 'Overlord'. In this story, the main character is Momonga, who is a powerful lich. He gets trapped in the game world he was playing, and his journey to explore and dominate this new reality is really engaging. The story is filled with interesting characters, both friends and foes, and the world - building is quite elaborate.

I recommend the novel I'm Really Not Pangu to you. The main character was a Black Iron Human with golden divine marks on his body. He rose from the bottom of the sky and dominated the galaxy. In the war between the gods and demons, the Human King died in battle, and the fate of the human race collapsed. All races were not spared. He carried an egg and constantly searched up and down. The story was full of thrills and excitement. I hope you like this fairy's recommendation. Muah ~😗

There is no romance or romance. 2. " Professor Lu stops me from spending money every day ": The protagonist was originally a love-struck fool, but after transmigrating, he became smart and no longer love-struck.

😋I recommend the following novels to you: 1.

He was a spy in the Ghost Killing Team. 2. <<Strong Spring Intent>>: Ye Qing, who has been reborn as a demon, wants to live in peace and become an immortal, but she attracts the pursuit of demon experts. Let's see how she deals with it. I hope you like my recommendation, Mwah ~😗

One such light novel is 'The Ancient Magus' Bride' where the MC is a humanoid spirit. The story is captivating and the non-human MC adds a unique twist.

One interesting 'Harry isn't human' fanfic could be where Harry is a powerful elf. In this kind of fanfic, he might have enhanced magical abilities that are unique to elves, like extreme speed and an even deeper connection to nature. Another could be that Harry is a dragon in disguise. He would have the strength and the ability to fly, which would change the whole dynamic of the story. And there might be a fanfic where Harry is a phoenix, being able to rise from ashes and having the power of healing and prophecy.

One interesting idea could be exploring how Lucy, not being human, views the human world. Maybe she has unique perspectives on human emotions like love and friendship that are different from our own.

One interesting 'eren isn't human fanfiction' could be where Eren is some kind of ancient spirit reborn.
