Somehow the idea of 3 minute rounds with rest periods does not apply to the finals.
The match concludes with 0:15.45 left on the clock.
On Yuko's monitor is the status board showing 9:00 minutes in the match. This is inconsistent with the matches being three 3-minute rounds.
When the operator opens the Elevator Door for Kotaro and Tamayo you can see Ran Mouri and Shinnichi Kudo from Detective Conan in the background.
Hatoko tells Kotaro to put suntan lotion on her back, but as she flips over, her bathing suit covers her whole back.
The scoreboard displays Shuji Inada's name as Syuji.
The match ends with 28 seconds to go.
Misaki learns for the first time of Icchan's position in Angelic Layer, even though her friends already know who he is.
Shuji Inada designed the Layer for this episode. His wife Yuko says it is from his "ship in a bottle" building hobby.
The National Finals format has three rounds and one minute breaks between rounds. Although Sai's match in the previous episode did not follow this format, Hikaru's match seems to be consistent.
What time is it again?
In the battle between Eagle and Shirahime, the scoreboard above the arena has inconsistent markers for Time Remaining.
At 7:46 remaining, Shirahime goes into Hyper mode.
At 3:29 remaining, Eagle took a bunch of blows and is looking for Shirahime.
Shortly afterwards, Shirahime does her finishing attack.
At 4:39 remaining, the match ends.
This contradicts the 3-minute 3-round format that the final games abide by.
Also in the final scoreboard display of the match, the scoreboard text shows eagle vs. suzuka.
DVD Coordinator Mariela Ortiz notes that near the end of the party, when the angels are sitting on a table, Kaede's angel Blanche is missing, but in another shot, Blanche is next to Shirahime.
Arisu is the Japanese version of Alice.
Ryo Misaki's angels are all male. He uses a different angel for each of his battles.
He and Shuko are the only ones so far who have more than one angel.
A woman is shown sitting in a wheelchair, which is a key plot element in this anime. In the manga, the same woman is introduced much later, and she can walk and run around.
The english dub uses the -kun and -chan honorifics.
Misaki Suzuhara calls Ryo Misaki "Misaki-kun"
Tamayo still calls Kotaro "Kotaro-chan".
Ichiro calls himself "Icchan" when he's around Misaki.
Regional Tournament remarks:
1. Each player plays up to ten battles in the qualifying tournament.
2. Four players were chosen to advance to the Kanto tournament. Each represented a compass direction.
3. Misaki could not lose a second match in order to still qualify.
Maria named her doll Tsubaki, which is Japanese for camelia.
Misaki's last battle is numbered Battle 23, although Misaki has a record of 8-1, and Maria has the same record as her. This breaks the previous numbering scheme where the participants' battle number followed the people playing i.e. Misaki's first match was battle 1. Vasquez vs. TJ match was also battle 1. Logically this battle should have been battle #10.
Hikaru fought TJ, who had lost to Vasquez earlier, implying that this particular tournament is not a traditional single bracket (one loss and you're out) or a traditional double elimination bracket (one loss puts you in the loser's bracket, another loss and you're out).
