The former Phantom Thieves reuniting for so long in person is a nice moment at the start of the chapter. It helps that they are going to the Summer Olympics as longtime friends.
Mentions of Hifumi taking care of Sion allowed him to slowly open up in getting used to living in Tokyo.
Despite the seriousness of the current story, it is nice to see some of the Phantom Thieves and their friends went to Universal Studios Japan.
After stopping a Yokai and Lost skirmish, the heroes are having a celebration by eating food. This is a similar tradition seen in Persona 5 whenever they recruited a new member at a time, now they are doing this to officially celebrate Sion.
During the celebration, the Phantom Thieves recount Hifumi and Sion (While Yumeko is not paying attention) about their past events as vigilantes stealing hearts from corrupted adults; going from the foundations by stopping Kamoshida, to unite against Shido, and eventually stopping Yaldabaoth.
