Here's a picture of the Next Challenger Determination Tournament from the OZ Academy page. Some of the bracketing is a bit different than has been posted, although none of the first round match-ups have changed. Remember, first round matches have a 10 minute time limit, so expect a lot of GAEA-style sprints.
In case it's hard to see the image, we've got this:
#1: Dynamite Kansai vs Takako Inoue (10/8)
#2: Sonoko Kato vs Manami Toyota (10/8)
#3: El Blazer vs Ryuma (10/21)
#4: Ran Yu-Yu vs Chikayo Nagashima (10/8)
Winners of #1/#2 and #3/#4 meet in quarterfinals on 11/23; those winners meet in semifinal on 12/16.
#5: Toshie Uematsu vs Sayuri Okino (10/14)
#6: Kyoko Kimura vs AKINO (10/21)
#7: Hiroyo Muto vs Yumiko Hotta (10/21)
#8: Kaori Yoneyama vs Carlos Amano (10/21)
Winners of #5/#6 and #7/#8 meet in quarterfinals on 11/23; those winners meet in semifinal on 12/16.
The final is also on 12/16.
