This is oddly funny because it's true. Crazy fans have a tendency to bash new characters (especially new female characters) before they even know what the character is like mostly because they believe that new and different is bad, and because the new female characters render their sickening yaoi fantasies a pointless and wishful thought. Even though AkuRoku was already a wishful thought for crazy yaoi fangirls before Xion showed up due to Namine.
I feel really bad for her. Unlike most people, I enjoyed 358/2 Days, and I liked Xion. I even made a rant on YouTube defending her recently. But nevertheless, this comic speaks the truth.
