Ralsei casting a pacify or healing spell, complete with sparkling star effects.

Furthermore, the Shimeji Ralsei operates as a low-stakes, always-available portal to the Deltarune universe. Unlike launching a full video game, which requires time, focus, and narrative commitment, a Shimeji exists passively on the desktop. It is a constant, silent companion during work, study, or browsing. In an era of digital isolation and remote work, this persistent presence offers a unique form of parasocial interaction. Psychologists have noted that “ambient intimacy”—the feeling of being connected to someone through small, constant cues—can reduce anxiety. Shimeji Ralsei provides precisely this: the sight of a fluffy, bespectacled prince sliding across a spreadsheet or napping on a browser toolbar injects a moment of whimsy into the mundane. He asks nothing of the user except their passive awareness, embodying the game’s core theme that kindness is not a transaction but a state of being.

Unlike a static wallpaper, a Shimeji is interactive: it can walk on your taskbar, climb your browser windows, sit on top of your folders, and even "steal" and throw your windows if you aren't careful. Why Ralsei is the Perfect Desktop Buddy

Your desktop windows become a playground. Ralsei will walk across your taskbar, scale the side of an open Word document, and hang upside-down from the top of your screen. The climbing animation usually shows his little gray horns bobbing up and down.

Indie game platforms are surprisingly good for desktop buddies. Many fan creators host their Shimeji files here because these platforms scan for malware. Search for "Deltarune desktop buddy."
