Zen Toono
Zen Toono is a quiet, reclusive guy with an unusual obsession: he spends his time hunting down stray cats. What makes him stand out, though, is that he's constantly trailed by what appears to be a whole mob of furious cat spirits—and yeah, they seem genuinely pissed off. Whether they're actually angry or just look that way is anyone's guess, but they're definitely always there, following him around like some kind of supernatural entourage.
