Her intro had me laughing so hard I was almost crying, it was expertly crafted, and then there was her one dorm event at the end that gave me a very deep understanding of what it looks like she is going through at the cost of more "Delirium" flashbacks. It is a cost I would happily pay, though. She needs help just like every other girl in the cast and in order to help her, her problem must be understood, which means being exposed to it firsthand.
She is just way too fun to mess with, it brings out the mischievous devil in me, which is the exact opposite of the other girls or when dealing with Niki in person. Fun fact, her personality is my second least favorite to the more hostile version of Touka's. Touka is a himedere, does the whole princess/commoner thing, looks down on anyone not at or above her status, usually comes from some form of higher status family. The only difference between Touka and a typical himedere is that she doesn't seem to look down on those of lower status on purpose, that's just the way she was raised. She sees them as less fortunate, but not necessarily under her, which is a good thing in my eyes. Niki is the stereotypical celebrity type, which I hate almost as much because of their bitchy attitudes. For that reason as well as her bullying, that's why Yumi still stands in last place, though she has grown on me now that her undeserved hostility is calming a bit.
