All of the characters who have made it past the nomination period has now been ordered into sixteen groups to present the first part of the preliminary period. Credit goes to akumaxx for providing the full list of how the preliminary period will look like. The link for the page is here. Again, this is in Japanese, as an English translation as not been provided yet. One can use the translated list chaosprophet as provided in the previous post and make a list from there. The match is supposed to begin today or tomorrow, but I would give it two or three more days to see the preliminary period up and running like crazy.
Edit: Translations for all characters within their groups are provided here. A big thank you to chaosprophet for translating all of that for us once again and putting it in order.
