During the montages of the school festival near the end of the episode, a girl who greatly resembles Rikka Takarada is seen sitting near the school's Chorus Club members as they perform as part of the event. It's ambiguous whether this student being Akane Shinjo's real-world self since her actual appearance confirmed to resemble Rikka and that the series being arguably set in the real world unlike the previous installment.
In the scene in the school festival where Yomogi shows his mother and Kamijo around, a poster of Cyberpunk Edgerunners can be seen in the background.
