I myself would like to see a Lot more ToAru Majutsu no Index.
It'd be interesting to see if Touma begins to take interest in Misaka.
Also, I'm starting to wonder what's going on with Index and why
she's been left as a "minor character" for the majority of the second
season. Maybe they should've called the series ToAru Majutsu no Touma instead.
Then again, It'd be nice to see more Hayate. J.C. Staff started to actually give the series a direction once they took over. I wonder if Hayate will choose Nagi or the Hamster... but maybe he'll go for Maria or someone else instead.
Will his parents come back?
