I saw this on a bandori confessions blog on tumblr and I had to post it because it's pretty accurate and on-point.

A friend of mine really dislikes Chisato and claims that her character is "inconsistent" (and then goes "lol I don't hate her, I just don't find anything to compliment about her"), when asked why he thinks that, he said he's basing Chisato's character entirely on Pasupare's first band story. And when I told him that she gets more chara development in later event stories and card stories, he said he refuses to read them. Meanwhile his favorite Bandori girl is Himari, a quite simple character. (No offense to Himari lol.)
