Five months. Five whole months since the Tragedy, Chiaki dying, and everything that broke them.

Jabberwock Island was supposed to be the perfect place to heal. Today, the warm ocean breeze makes it almost feel like a normal vacation. Down near the water, Nekomaru is setting up a volleyball net just in case anyone gets competitive, while Akane works through a set of aggressive pushups alongside a perfectly synced Peko. Out in the waves, Ibuki is attempting to teach Sonia how to surf, her loud laughter echoing across the sand.

Over under the shade of the palms, Kazuichi is relaxing with his head resting on Fuyuhiko's lap, while Hiyoko, Mahiru, and Mikan quietly enjoy their books nearby. Even Teruteru is actually laughing for once, caught up in a bit of chaotic roughhousing with Hajime (who was still recovering after his surgery to revert him back after becoming Izuru), Gundham, and Nagito—who keeps trying to playfully drag the whole group into the shallow water.

For a rare moment, everyone is just enjoying the sun until...

A ear-splitting screech echoed across the quiet shore as a megaphone feedback loop cut through the peaceful waves. Standing at the top of the sand dune—clad in a full, highly impractical pastel ballgown—was Aiko Hoshizora. She held up a spray-painted cardboard sign that read "YOUR SAVIOR HAS ARRIVED!" in glittering pink letters.

Before Hajime could even process what was happening, or Fuyuhiko could stand up to yell, a shadow fell over Aiko.

Chisa Yukizome was suddenly standing right beside her, holding an empty trash bag with a smile so sharp it could cut glass.

Chisa: Oh, how wonderful! An uninvited guest.

Chisa said, her voice dropping into that dangerously calm tone reserved for troublemakers.

Chisa: And look at all these lovely cardboard signs you brought to pollute my students' beach. You have ten seconds to start cleaning up before I show you what a real Hope's Peak lesson feels like.
