Dunno if this was strategic, or the strength of Nodoka, but Shana Falls.
Quarter Final 3
1st 946 Nodoka Haramura @ Saki
2nd 890 Shana @ Shakugan No Shana
By 50 votes: Nodoka knocks off Shana.
…This could either one of two ways: A Strategic victory for Aoi or an Azunyan win to set up the first Saki Matchup. I think that Azunyan has this one.
