Yuri... hmm... i think this is possible. Why? 'Every' male in the series love lolis, so nobody love poor Kaori-chan.
I guess there'll be a little fanservice, or a 'Kaori-loving' episode. You know: the ice girl, some idiot main character, ecchi, sleazy clothes... or just it'll be too typical?
Or not, and just the lolis take the whole stage?
We will see it...
Kaori relationship with Index also interesting, and i hope, we will know much more from this two character across Kaori.
