This is a very simple OP main character story with really good art. Character wanted to become an adventurer, but can't, and then his useless power ends up being the key for him to become the most OP character possible. Since the main characters almost don't have any flaws, and even the slight ones they have by being unexperienced or social awkwardness, never actually become an issue or might just disappear at some point as they get stronger. Keep in mind that when I write this, this manga is still being published and still didn't develop much (even though it's been an year since it begun).
Since this is a VERY common type of story, there just isn't much more I could say that anyone that reads manga wouldn't already know. It's just the same as every other manga of this kind. But the story is is very decent, and I do care for the characters' motives.
It is very light hearted, and even though many are tagging it as "harem" (and it kinda follows that genre's formula), it is not ecchi by any means. And the mc is not an arrogant douche as they often are. So if you like silly and funny stories with good art, this might be a good choice for you.
