Blue Storm is a demon who exists to protect Ritsu, except neither of them really knows what they're doing half the time. The show treats that friction as the actual horror, not jump scares or elaborate mythology, but two people with power they don't fully understand trying to fix problems that don't have clean solutions. Every standalone mystery folds back into something quieter: people dealing with the supernatural because they have to, not because they chose to. This is what happens when you inherit a gift you never asked for and a guardian who's just as confused about the job as you are.
Ritsu carries a burden passed down through his family: the ability to see what others cannot. His grandfather's final gift comes with strings attached, namely a cantankerous demon named Blue Storm who's bound to protect him whether Ritsu likes it or not. Together they navigate a world where the supernatural bleeds into the ordinary, where neighborhood curses and vengeful spirits treat normal streets like hunting grounds. Each encounter tells its own complete story. A possessed convenience store. A cursed photograph. A ghost that won't leave its favorite restaurant. What connects them isn't plot threads but a shared cast of characters learning to coexist with the unexplainable. Some seek answers. Others just want peace. Ritsu and Blue Storm find themselves mediating between worlds, untangling mysteries that defy rational explanation. The tone walks a careful line between genuine dread and wry humor, never letting either fully take over. This is horror that trusts you to feel uncomfortable, paired with characters grounded enough to keep you watching.
