For me it's Leslie from the promised Neverland. It was only seen in one scene but I immediately loved it

I dont know why but people dont seem to like her that much.I geniuenly think she was fun.She wasnt that useful but at least she was a funny character and she was kinda insprational in the 5th chapter.
I find that I love most characters that people hate. A lot of the time, people will confuse "bad" and "dislikeable" where in this context, they are completely different. If I had to put out one example, it'd have to be Rachel from Tower of God. She is a character that I personally love, almost as much as Bam, and it bugs me when people say, "she's such a bad character." She's simply not. Rachel is written in such a way that she completely boils our blood, and suddenly we have this fuel of hatred for her, that we just want her to fail in life, no matter what it takes we want to see her fail, and I think that in itself is such beautiful writing by SIU. We are so engulfed in our hatred for Rachel that she, herself, is actually a huge part about why we enjoyed Tower of God. And, that's something that a lot of people fail to realize, is that for most of the audience, Rachel is the exact reason why you are reading/watching Tower of God. That's why I love dislikeable characters, because of the beauty of their writing.
Zeno from Akatsuki no Yona. Since more people seem to watch anime than read manga on this site, people don't know how great of a character Zeno is because he showed up for only one episode in the anime series. But he had an amazing character arc in the second half of the ongoing manga and I hope there will be a second season to showcase Zeno's character in more depth.
Kumatetsu from Bakemono no Ko


Zeno: As a user above said, he's only less popular because non-manga readers
barely know him. But there's SO MUCH going on behind that childish smile of his ~
Leorio Second fave from HxH. Sure he's not physically strong, but he took
the Hunter Exam to become a doctor so being a doctor is what makes him
cool. Plus, he's the dad of the group always worrying for everyone <3
Totsuka: Favourite K Character. He's a lot like Takemichi in how he's physically weak
but has an open/kind personality that gains the love and respect of an entire gang of
thugs. Dead before the anime even begins, still my fave from it.
