..I accidentally got spoiled last year, but it's no big deal to me. I'm sure when I get to that point in the series (I'm at ep2 of Origination ATM), knowing what happens won't decrease my enjoyment at all.

Akari vs Hina is painful, and I actually do like Hina more than Akari, but if Akari is still in the running for the necklace by that point, I'll still vote for her.
Luckily I know most of the characters in this tournament, this time around (last year was kinda pathetic). I'll try to finish at least F/SN and Bamboo Blade by the time the main tournament starts.
