Actually Yeah One Character Does Come To Mind in this situation.

mc!!! how dare you use shizuka's icons for this question!!! she's my favorite character you know v.v. and yes i don't really like kohta(sorry :P) or sochiro or that bastard koichi. those are the only ones though.

^ I wanted to use a picture to fit the words sorry..these were the only ones I could think of finding,sorry :p

That creep of a teacher and all the students who followed him, they needed to be eaten by the zombies. Also I don't really like Shizuka, she gets on my nerves.

Shido. Hands down. I'd feel safer with the zombies than on the bus with that mattaku no baka!

I hated Shido and i didnt really like Shizuka :|

i dont like saeko im sorry! there is something about her i just dont like :(

hate that dumb teacher and that at the gas station.(what a creep)

Komuro. He seems like a perv getting angry at the girls a lot but when they're alone he embraces them and all that crap.

I didn't like Shido, the students that followed him, and the rapist. I guess the zombies don't really count as characters. Shizuka was okay to me; I thought she was just there for comic relief. I thought it was hilarious when she punched Kohta with her boobs, lol. The only thing is is that she's not very helpful in life-threatening situations. :)

i do not like rie

i dnt like saeko at all!!!

Shido (obviously(, the rapist guy (he was a normal guy who was actually mentally affected tho), (idk why ppl dont like Saeko (she's nice and I like her) and y ppl dont like Shizuka as well (I agrre with @Sweetlyspice about her, I think its for the humour and she's funny and stupid xD), and I kinda dont like Rei (She seems kinda annoying and stubborn, but in any case I don't HATE her, I just don't like her....)

I soooooooo HATE Saeko! There is sooo much I don't like on her. But she can fight good.

Shido and his students(I'd rather hug a zombie than be on that creepers damn bus)
Rei (she is so bipolar it's not even funny, one second she loves Komuro the next she hates him and she just seems like a gold digger but instead of money she wants power (dating the most popular guy)idk that's just me)
Takagi(she is so conceded when it comes to how smart someone is)

other than that I like the characters

I guess the teacher was the only one I didn't really care for.
I actually like Shizuka.
