Play ミラーブレイク：虹の向こうへ on PC and Mac

Mirror Break: Beyond the Rainbow is an action RPG developed by Kunpan Games, set in the glittering yet dangerous fashion city of Gabien, where psychic powers and hidden desires collide beneath the surface of a mysterious mirror world. Players take on the role of director of the Spirit Research Institute, navigating a story-driven journey through a reality fracturing under the influence of a rainbow eclipse. The game blends vertical screen combat, branching narrative choices, and a cast of unique psychic characters into a single polished experience, and every bit of that can be enjoyed on PC by running it through MuMuPlayer.

At its core, Mirror Break: Beyond the Rainbow offers fast-paced one-handed touch battles that translate beautifully to a larger display, with flashy skill combinations and powerful special moves lighting up the screen each time a mirror is shattered. The roster of playable psychics comes from diverse backgrounds including researchers, police officers, prosecutors, and students, each reborn with abilities that make them formidable allies in battle. What truly sets the game apart is its branching storyline, where every decision you make steers the outcome toward either preserving order or embracing the transformative power of the rainbow eclipse. New players also receive up to 110 free gacha spins at launch, giving an immediate and generous head start for building a strong team.

Playing Mirror Break: Beyond the Rainbow on PC through MuMuPlayer brings several meaningful advantages to the experience. The larger screen makes the vertical battle system far more visually impressive, letting every special move and skill chain hit with full impact. MuMuPlayer's stable performance ensures that fast-paced combat sequences run smoothly without the battery drain or heat concerns of a mobile device. Keyboard and mouse controls can be mapped to streamline gacha pulls, skill activation, and menu navigation, making the overall session more comfortable during extended play. For a game built around deep story choices and team-building, having the reliability of MuMuPlayer behind you means you can stay fully immersed in the world beyond the mirror.

About the Game

Step into a city where glamour masks something far more unsettling. Mirror Break: Beyond the Rainbow is an action RPG that places you at the center of a crisis unfolding in Gabien, a sprawling fashion metropolis where the boundary between reality and a hidden fantasy world has begun to crack. A phenomenon known as the rainbow eclipse is bleeding into everyday life, and the glittering surface of the city conceals truths that most people are not ready to face.

You are the newly appointed director of the Spirit Research Institute, an organization thrust into the middle of this unfolding crisis. The rainbow eclipse is not a natural event, and the mirror that reflects the darkest corners of the human heart is not simply a metaphor. As strange occurrences escalate across Gabien, it falls to you and a group of extraordinary individuals to investigate, fight back, and ultimately decide what kind of future this world deserves.

The Characters You Fight Alongside

The allies who join your cause are not born warriors. They are ordinary people from all corners of society who have been transformed by the circumstances of the rainbow eclipse into powerful psychics. Among your companions you will find:

Former researchers who turned their analytical minds toward combat strategy
Prosecutors and police officers who channel their sense of justice into devastating abilities
Students who carry the weight of an uncertain future into every battle
Individuals from walks of life that give each character a distinct personality and motivation

These characters are not interchangeable fighters. Each brings a backstory, a reason for being there, and a relationship with the conflict that develops as the story progresses. They answer your call and fight beside you, and the bonds you form with them shape the tone of the entire experience.

Combat Built Around Impact

Battles in Mirror Break: Beyond the Rainbow are designed for the vertical screen format, keeping the action immediate and tactile. The core loop revolves around destroying mirrors, and each shattered mirror pulls back another layer of the illusion that covers the city. As you fight, skill combinations open up, letting you string together abilities in ways that build toward overwhelming special move sequences. The result is combat that rewards both quick reflexes and thoughtful team composition, all controlled through simple touch inputs that feel purposeful rather than shallow.

A Story That Responds to You

Narrative choice is woven into the foundation of Mirror Break: Beyond the Rainbow rather than added as a surface feature. The decisions you make throughout the game do not simply affect dialogue. They steer the entire direction of the story toward one of two distinct paths. You may choose to act as a guardian of order, protecting the existing world and the people in it. Alternatively, you may embrace the power of the rainbow eclipse and guide humanity toward a transformation that no one fully understands yet. Neither path is presented as straightforwardly correct, and the tension between them is what gives the story its weight.

The World Behind the Mirror

Gabien is a city designed to look desirable from the outside. Its fashion culture, its ambitions, and its social hierarchies all project an image of success and beauty. But beneath that surface, the mirror world operates by different rules. Desires that people hide in waking life become tangible forces in this space, and the psychics who venture into it must confront not only external enemies but the reflections of something internal. The game uses this contrast between the polished city exterior and the unstable mirror world interior to build an atmosphere that feels genuinely distinctive.
