Anime characters are either being hated or loved. It depends on their personality and contributions in the story. There are characters that are being hated for various reasons. Most of them are of course villains or protagonist. But there are main characters that are being hated too. Maybe they do something that a protagonist shouldn't. And some just hate the characters for no other reasons and its so stupid.
But actually, there are so many characters that you can't just hate. Everyone loves them and if you don't, you can't find any reasons to hate them. And here's the characters that I personally think no other reason to be hated.
Chika Fujiwara
Anime: Kaguya-sama wa Kokurasetai: Tensai-tachi no Renai Zunousen
If you hate this character, man you should really ask your self if you're okay. Chika is my most loved character in Kaguya Sama: Love is War. She is cute, cheerful, friendly and easygoing. She may be dumb sometimes but that's what makes her more adorable. The show looks more fun because of her presence. And your frustration from the roller coaster relationship of Kaguya and Miyuki will gone all just because of Chika.
Hatake Kakashi
Anime: Naruto
You may hate him because of Rin incident. But if you know the backstory you can't find any other reason to hate him. I like him first in the Zabusa arc. And later in the story, this character never disappoint us. He is always present in any major arc. And his contributions in the story is immeasurable that makes him deserving for the Hokage title.
Raphtalia
Anime: Tate no Yuusha no Nariagari
Definitely the character you can't hate. Why hate Raphtalia? She started into a very cute loli and later she grows into a fine beauty. She is very admirable, despite of all her hardship in life (sold as slave and witnessed the death of her parents) she still got a very gentle and kind heart. Seeing her presence in anime makes your day more brighter.
Kanna Kamui
Anime: Kobayashi-san Chi no Maid Dragon
Shame on you if you hate this adorable little dragon. Her presence alone will make you smile and melt your heart. The way she talk and behaves is so cute. Given by her appearance and design, you can't find any reason to hate her. If you just want to just have a good vibes, why not watch this anime and bless your heart by the character of Kanna Kamui.
Ginko Mushishi
Anime: Mushishi
You may think that I'm just being biased here because I like Mushishi (well it's true though). But seriously Ginko is just a well developed character that you can't just hate him. He always do his best to help the problem of people about "mushi" and even put his self in danger so that he can solve the problems. He may fail sometimes but he did what he thinks best and you just can't hate him because of that.
Nezuko Kamado
Anime: Kimetsu no Yaiba
There may be some haters of Demon Slayer but if they also hate Nezuko because of that, I think those people are just unreasonable and complete stupid. She can be cute, scary and protective and it's only the reason to love her. If you have a reasonable answer why you should hate Nezuko, just comment it down below.
Shigeo Kageyama
Anime: Mob Psycho 100
You can hate other characters in Mob Psycho 100 but Shigeo isn't a hate material. He may look like an airhead and can be easily manipulated but he got a strong sense of justice. His belief is reasonable and always side on what is right. I don't know if there is someone out there who hates Shigeo. But if they do, I doubt if they have in their right mind.
Nadeshiko Kagamihara
Anime: Yuru Camp
I think all characters in this anime is lovable. But Nadeshiko is on another level of love. She is very similar to Chika Fujiwara and you can't really hate her. Since episode 1 you will just love her especially the part where she slept in the road. And when she started to eat, she looks way more cuter that you might think that the food that she eat is very delicious too. Another anime for good vibes, you have to check it out.
Mayuri Shiina
Anime: Steins;Gate
Okay, the "Tutturu" line of Mayuri is just so cute. I wonder if there is someone who hates her. She is just a character you can't hate. If you've watched Steins;Gate you'll know the reason why. She is innocent and childish that you will never like what will happen in the story.
There are still tons of anime characters out there that you can't really hate. Some are still in the Manga or Light Novel that are waiting to be discovered. So if this article reach at least 8 likes, maybe I'll make a part 2 and include some manga character.
Can’t argue at all with the list hehe
