Rinne's disability isn't tragic backstory, it's her actual lens on the world, which means every revelation about what's happening around her lands differently than it would for you. Jugemu shows up to save her and never explains himself, so the entire show becomes an investigation into whether you can trust someone who operates on information you don't have access to. The bond they form isn't romance or mentorship; it's two people learning to navigate worlds that are actively ending, one unanswered question at a time.
Rinne has lived her entire life unable to see human faces, a curse that defines her existence. As the latest member of an exorcist family, she prepares for her first assignment with grim determination. Instead of the routine supernatural work she expected, she stumbles into a catastrophic encounter that nearly costs her everything. A figure named Jugemu pulls her back from the brink of death and reveals a terrible truth: countless realities known as Strike Worlds are collapsing into oblivion. Together they traverse these doomed dimensions, racing against time to understand what's destroying them. As Rinne and Jugemu journey deeper into worlds on the verge of extinction, something unexpected develops between them. She begins to see past her affliction in ways she never thought possible. What started as a rescue becomes something far more complex, forcing Rinne to confront whether she's truly powerless or if her curse holds a strength she's never unlocked. The mystery of why she was chosen, and what Jugemu really knows, deepens with every world they leave behind.
