Well, like most of these "OP MC who doesn't realize he's OP get banished from his party (or family, here)", it started with a pretty low bar for expectations. At least, in fantasy world, there's an excuse for magical/superhuman abilities, but that supposed to be the real world. Him doing the work of a whole agency by himself was already stretching the limits, but now, the Aikido mastery and the Quicksilver-like ability to sew patch on someone else pants unnoticed, made sure it crawled under that low bar instead of stepping over it.
I don't care about the MC who will add girls to his harem by making them succesfull while denying having any influence and will remain totally oblivious throughout any advance those girls will attempt.
But, at least, there might be a bit of originality and variety (since they all got different jobs) in how each of the sisters and the mother meet their demise compared to the usual fantasy party failling all their jobs and getting demoted/destroyed by monsters, so I'll stick around for that part.
