On one hand, more lewd shots of Best Girl always appeal. Can't exactly ignore that.
But on the other hand, Worst Girl is still bullying her. That wasn't okay before and it isn't okay now. Chiaki really needs to leave Reiko the fuck alone.
And on an unrelated note... why would anyone want to keep an eel?
@himeleth : Aren't you that loser who likes Chiaki? Well, at least you're consistent with your bad taste. =p
