Sei covered this in the above blog. ^^^

''"The way it will work is this: I will start with my own introduction. The next one will be the 2nd Division Captain. They will either make a continuation of my post, adding to the scene, or making another scene shift, depending on how they feel about it. Then the 3rd Division Captain will post. And then 4th. 5th. And so on and so forth, all the way to 13th, in that order. When it is your time to post, you are welcome to use whatever officers you wish during your post, so long as your Captain is a main focus.

I think this will be a nice way to stretch out our writing muscles a bit and get accustomed to each other's roleplaying styles a little.

Once all 13 Divisions have posted, Blank will make the next post with Hiyori entering the Soul Society; all cut up and bruised, of course. It will be at this point that she will encounter a Captain or other significant officer, depending upon who manages to post first; at this point, posting will be up for grabs until somebody brings the situation of Hiyori to the Head Captain. Then I will post, announcing a Captain's council."''

So, to answer your question, the Captain of Squad Two posts next. So Abysmal Shadows.
