^ You have a point about Minami. There's a purity to her vicious pettiness, malice, cruelty, and back-stabbing that really does reflect the worst aspect of Tomoko's personality. I think that's why she avoids and probably fears Tomoko, beside the fact that Tomoko has friends Minami doesn't want to cross and probably heard Tomoko's loud comment about her being a "little fanged girl."
