Invitation to Everlasting Summer

Team Q4 and friends travel to a distant southern deserted island with an invitation from the VF Circuit, but when they arrive, they learn that Team New AL4 has also been invited. While Team Q4 is fixated on training to get stronger, everyone else is looking for some rest and relaxation. Later that night, after dinner, Ren gathers everyone together and gets them to agree to be in a test of courage, with some having the job of scaring people and the others being put to the test. Shenanigans ensue such as the supposedly-stoic pair of Misaki and Asaka easily getting scared to the point of fainting and Kamui failing to scare Tetsu for being paired with Emi. Aichi and Kai are teamed together to go through the course, but instead of doing so, Kai takes Aichi off on his own and gives him some words of encouragement, which are topped off by a fireworks display.
