The students of Shujin visit Hawaii from September 7th to 11th. Students from Kosei High School also spend their school trip in Hawaii, as their plane was re-routed from Los Angeles due to inclement weather.
Here, the Phantom Thieves find out that their popularity has traveled outside of Japan into the United States, and most of the beach-goers know of their exploits. The students also discover with dismay that most things are not that different from home; for example, they eat at a Big Bang Burger, just like they already do in Japan.
The protagonist may spend time with one Confidant at Waikiki Beach on September 10th—either by way of a date with one of the girls, or by hanging out with the guys. The only exception is Haru Okumura, as Hawaii's events happen prior to Okumura's Palace, where she makes a proper appearance.
In Royal, the protagonist can interact with Haru, before she interrupts Kawakami posing in a bathing suit in her hotel room. A surprise encounter with Kasumi Yoshizawa also happens in the souvenir shop, and is the first time the other Phantom Thieves meet her.
All dates with the female cast involve tasting a local delicacy: Garlic Shrimp. Each date will make a comment on the delicacy, and find out from the stall owner about the popularity of the Phantom Thieves.
