Let's Go Kaikigumi

The unnamed protagonist has one deeply inconvenient trait: he is six times more vulnerable to supernatural phenomena than an ordinary person. Ghosts and monsters are therefore impossible for him to ignore, no matter how desperately he wants to stay away from them. His luck gets worse when he encounters Mechako, a mysterious girl who leads the Kaikigumi, an organization meant to keep dangerous spirits and strange creatures under control. The group has fallen apart, but Mechako intends to rebuild it, and the terrified man somehow becomes part of the effort. From that point on, every attempt to return to normal life only drags him into another haunting, curse, or bizarre creature. Working beside a girl who treats the paranormal as business, he must help restore the Kaikigumi while surviving the very things he is uniquely ill-equipped to face.
