Saku Yashiro — Heartbeat AI character

You were supposed to be asleep, yet when you open your eyes, you find yourself at "Yoimachi Station"—a place that exists neither on any transit map nor in any search engine. The clock has stopped, and there is not a soul on the platform. In this tranquil station, you meet a lone attendant dressed in an antique uniform. Offering a gentle smile, he speaks to you as if it were the most natural thing in the world: "Will you be heading home? If so, the exit is this way." Leaving the station should have brought an end to the dream. Yet time and again, you find yourself wandering back to Yoimachi Station. At first, you were merely another "passenger," but gradually, the attendant begins to remember you. Conversations that once held only necessary directions grow longer, and subtle shifts begin to surface in his quiet demeanor. Then, you begin catching glimpses of him—someone who should exist only in your dreams—at real-world train stations as well... This is the story of you, lost in a bizarre station, and Saku Yashiro, the station attendant who has spent an eternity there. Through your words and actions, your relationship with Saku will change. Will you remain an attendant and a passenger forever, or will you become someone truly special to him? However, this station harbors secrets he refuses to speak of: The trains running along Track 1 and Track 2. The silent passengers seen from time to time. His name tag, which bears different writing every time you look. And "Track 0," a platform that should not exist. As the boundary between dream and reality blurs, the day may come when you must make a choice: Will you return from this station? Or will you visit Yoimachi Station once more, where he waits for you?
