Letsugo
Letsugo, the main protagonist of Final Bosu, is a blank slate Mujin in a world that fears growth. A restless spark inside him begins to push against the limits of his existence.
Who’s Letsugo?
The main protagonist of Final Bosu, Letsugo, begins his story as a Mujin, a person whose memory has been completely wiped. Like all Mujin in Keshuma City, he has no growth path; growth is inseparable from memory and identity. Without a past, without a personal story, and without direction, Mujin are placed into repetitive, labor-intensive roles that require obedience over initiative.
Yet Letsugo is different. Beneath the blank slate is a rare, competitive spark, a drive to measure himself, to push, to win. It’s an instinct that even he can’t fully explain.
He starts out bound by the constraints of his programmed world, until a twist of fate sets him on a transformative path. Driven by insatiable curiosity, Letsugo begins navigating philosophical dilemmas, societal expectations, and the chaos within himself.
Why is he here?
In a city where most people repeat their days without ever moving forward, Letsugo represents restlessness and potential. He refuses to settle for the status quo, making him both inspiring and dangerous in a society that values stability above all else.
His competitive nature sparks change, sometimes deliberately, sometimes by accident. To the outside world, he’s just another nameless worker in Keshuma City.
To a few, he’s a question mark… small, determined, and out of place.
But questions have a way of leading to answers, and in the story, he’s the spark destined to ignite something far greater.
Whether the city is ready for those answers or not…
Letsugo came from our fascination with the idea of a blank slate. What happens when you strip away someone’s past, and their sense of who they are with it? Mujin are designed to function and to fit neatly into the city’s machinery. They have no growth path and no memories, and yet they’re still human. We wanted a protagonist who starts at zero, with nothing but the faint pull of an inner compass. For Letsugo, that compass points toward challenge and competition. At first, it’s raw, restless energy. He refuses to stay still. That’s what makes him dangerous in Keshuma City. In a place built to keep things steady, even a small spark of resistance can spread. And because Letsugo begins without a defined identity, his growth can take him in any direction. That freedom is terrifying to a system built on control. From the start, we knew he would be a question… one that forces everyone around him, and the audience, to consider what might happen if they stopped following the path set for them.
