Lots of anime characters get more hate than they deserve. These ones have redeeming qualities that fans might overlook.

Then there are the characters no one likes, but in the middle are the characters that divide opinion, usually because there is a problematic angle to them that some can look past, while others cannot. Isekai has a couple of such characters, and they can really split fanbases right down the middle.

When Overlord first debuted in 2015, it was a good isekai with an OP protagonist and an interesting world. Fans were happy to watch Ainz make his way around the world and laughed at his occasional naïveté.

As the seasons went on, it became clearer and clearer that Ainz might not be the hero of the story, but rather a villain, and while some were able to appreciate this subtle shift, others were turned off by it. Ainz is so compelling because his reasons for evil can be explained in the context of the role he is supposed to play in this video game; a custodian of a race of monsters created by some of his best friends. It all makes Ainz a complex character, but also a polarizing one.

Cid Kagenou from The Eminence In Shadow was made to be polarizing. This series sometimes feels like a parody as it unapologetically leans into all the cringe tropes of modern isekai, including ridiculous levels of power, harems that make no sense, and morally ambiguous protagonists.

The Eminence In Shadow: The Strongest Members Of Shadow Garden

The Shadow Garden is a secret organization that seeks to control the world from the shadows. These are the group's strongest members.

While this certainly worked for some people, given The Eminence In Shadow got a second season and has a decent rating on MAL, it also rubbed some others the wrong way, as Cid represented something reprehensible. Cid’s flashy abilities and obsession with his hero persona can be very amusing, but considering it plays into the very real fantasy of some people sometimes gives room for pause.

Hajime is a normal 17-year-old summoned to another world along with his classmates, and while they get impressive abilities, he gets something that feels useless at the time. Not only that, he is also betrayed by his classmates and left for dead. He survives, gains impressive powers, and now has a harem. Typical, right? That's Arifureta.

The problem with Hajime is his quest for revenge against his classmates, which has led him down some really dark paths. This makes Hajime come across as unsympathetic to some who wonder why his anger fuels him to such an extreme extent.

Tanya Degurechaff from The Saga Of Tanya The Evil is a polarizing character for many reasons. First off, she is an antagonist as her actions don’t paint her in a good light. However, what really makes Tanya difficult to deal with for some is the simple fact that she is a grown man in a little girl’s body.

Some anime villains are very easy to hate. Here are some isekai anime that feature incredibly unlikable antagonists.

Originally a salaryman who was murdered and defied God whom he called ‘Being X’, Tanya is ruthless, mean, and her love for war makes her difficult to root for. Add to that the World War-esque setting of the show, which makes Tanya’s side seem very similar to the Nazis, and anyone can understand why Tanya is polarizing.

Sword Art Online is by no means the first isekai, but it was a show that grew so much in popularity that it's fair to say it was responsible for the huge fanbase that the isekai genre has today.

What makes Kirito so polarizing is that he was also the template for the isekai Mary Sue: a character so powerful, so ‘right’, that they never seem to have any real challenges or facets to their character. The ease with which the character does everything made a lot of people fall out of love with him, and he has been controversial ever since.

The Rising Of The Shield Hero was controversial from its very first episode. Released at a time of heightened social tensions, the subject matter of assault and false allegations is very tricky, and the show went headlong into its premise which rubbed some people the wrong way.

Naofumi, who was the one falsely accused of assault, then spends the rest of the first season angry, bitter, and sometimes downright unlikeable. His acquisition of Raphtalia was also viewed as slavery, and the fact that he has a harem just doesn’t sit right with some.

Rudeus Greyrat starts Mushoku Tensei Jobless Reincarnation as a jobless otaku who is a poster child for problematic behavior. He gets isekai'd into another world as a baby, and he decides to turn over a new leaf

while he grows into the role of Rudeus.

The thing is, for some, Rudeus is still a middle-aged man (since he kept his memories from his past life) and his amorous dealings with younger girls cast him in an irredeemable light. Rudeus does seem to grow as a character, but he never quite shakes the pervert tag he has earned.
