Kasumi is a very special character, and one of my favourites. She was also my first best girl and the reason I started playing Bandori.
I love many (if not all) things about her. Her design especially is awesome, even though we'll probably never know how she does that with her hair~ However, my favourite things about her are her personality and her passion.
Everything she's done feels so... effortfull? Is that even a word? But it really looks like she always gives it her best, and I really love that. She's more than just a Genki Leader, trust me. She puts so much passion into the band, into music, while at the same time having fun... it's honestly kind of contagious. Her smile makes me smile!
