Noblesse Oblige.

So it ended being Tousen who intercepts Shinji's attack. Oh, and did I mention everyone except Mashiro's mask broke because time ran out? Ya, it seems everyone can only hold it for 3 minutes, while Mashiro can do it for couple hours. Now if we remember back to Ichigo vs Grimmjow fight. Ichigo must have had held his mask for at least 5 minutes, and he kept re-creating it. So I don't know ... the Visoreds had their masks for a century and can hold it for 3 minutes, yet Ichigo had it for like half a year and suddenly can hold it for longer just because he has the main character hack.
Anywho, everyone jumps to battle and greet their opponents.

The match ups are:
Tousen vs Komamura and Hisagi
Halibel vs Hiyori and Lisa (Espada chick vs Visored chicks)
Stark vs Love and Rose
Barragan vs Hachi

Of course Aizen is just chilling again. Wonderweiss is absent-minded all of a sudden. I also think Hitsugaya might face off Ichimaru.
Soifon, Kyoraku, and Yamamoto are still up for combat for Soul Society.
Kensei and Shinji are the Visoreds that can still fight.
We can't neglect the chance that Urahara, Yoruichi, and Tessai will show up to help, since this seem to be one big family reunion.

It appears 4 Arrancars and 3 ex-Captains (assuming Aizen might do something) will be facing off with 8 Visoreds, 5 Captains (assuming Ukitake is down), and several Vice-Captains. No matter how you look at it this is not a even fight. I forsee Aizen's side getting a shounen boost or more reinforcements in the near future.
