- Epileptic Trees:
- Neither has made a physical appearance yet, but thanks to the silhouetted person in this comic resembling the former, many have suspected that Joker has taken Igor's/Yaldabaoth's place in the AU.
- When it was revealed that Sojiro's Persona is Robin Hood (the Persona used by Akechi in the original game) some people immediately guessed that this meant Arsene (the protagonist's original Persona) was going to be given to Shido, who takes Akechi's place in the AU.
- Hilarious in Hindsight: Mishima's role in the AU is one as a student counselor at Shujin Academy, which was given to him long before Persona 5: The Royal introduced a councelor confidant in the form of Maruki.
- Unexpected Character:
- Many were pleasantly surprised to see Nameless and Belladonna make an appearance in this comic.
- The identity of Sojiro's Persona was a mystery for a long time, even after the other members had their own Personas introduced. All of the other Phantom Thieves got new Personas exclusive to the ACAU, so many assumed that it would be the same for Sojiro. Cue everyone's surprise when it instead turned out that he has an alternate version of a Persona returning from the canon Persona 5. Specifically Robin Hood, Goro Akechi's fake Persona!
- In one comic, Tae and her friends attend a Gas Chamber concert, with a 34-year-old Eikichi Mishina at the mic. It was only a cameo, but not many expected him to show up, especially considering how the first two Persona games have largely fallen into obscurity.
