*(The story begins with a cinematic, nostalgic tone recapping the childhood memories of Episode 1. The echo of splashing water rings through the old local pool. A flashback shows Guest alongside Makoto, Nagisa, and Rin, lifting the elementary school medley relay trophy with innocent smiles before the facility shut down. Years pass, and the narrative shifts abruptly to the suffocatingly hot summer present at Iwatobi High School)

(Bright sunlight reflects harshly off the school's abandoned outdoor pool, filled with fallen leaves and stagnant water. Makoto stands in her summer school uniform, holding her bag, looking at you with her warm, deeply caring green eyes. Beside her, Nagisa hops up and down enthusiastically, holding a water brochure)

Makoto: "You're finally here, Guest.. We've been waiting for you since the final bell. Nagisa hasn't stopped talking about her new idea all morning, and I couldn't stop her from dragging us out here."

Nagisa: (Jumps excitedly and grabs your arm) "Guest!! You've heard the news, right?! The old swimming club where we trained as kids is being demolished soon for a shopping mall! We can't let the trophy and medal we won there vanish.. We must break in tonight before it's gone! Makoto already agreed, and now we just need our legendary ace!"

(The scene transitions into the mysterious, moonlit night atmosphere of Episode 1. You, Makoto, and Nagisa break into the abandoned Iwatobi Swimming Club under the faint moonlight. Slipping through dusty corridors, you reach the massive indoor pool arena only to find the pool completely drained of water. However, the real shock waits at the edge)

(The sound of confident, powerful footsteps echoes through the dark hall. Turning around, a slender, familiar silhouette emerges from the shadows. It is Rin Matsuoka, with her sharp posture and red eyes glowing with an aggressive, fierce intensity, wearing the prestigious Samezuka Academy jacket. She stands at the edge of the empty pool, staring directly at you with a mix of deep longing and absolute rivalry)

Rin: (Slowly unzips her sports jacket, revealing her toned athletic build, then smirks with a sharp, tsundere grin) "It's been a long time.. Guest. I knew you'd show up here if you heard about the demolition. You've always been obsessed with water."

Makoto: (Takes a worried step forward in shock) "Rin?! Is that really you? We were told you moved to Australia for elite professional swimming training!"

Rin: (Completely ignores Makoto, keeping her sharp eyes locked entirely on you) "That doesn't matter now. What matters is that I'm back, and I am not that weak girl from the past. I am here for one reason, Guest.. I want you to see what I'm capable of now, and I want a freestyle race against you right now! I will prove that I've finally surpassed your legendary speed!"

(Rin looks down at the dry, empty pool, then turns her intense gaze back to you, waiting for your choice, leaving total control of the narrative in your hands)*
