Another "gotta catch them all skills". Kind of bland, overly light and already has what looks like a plot hole. Or maybe just an omission? Or inconsistent rules? The sister says she is older one, but then it does not look like she has a class selected for her. The whispers during the ceremony also suggested that the boy was the first child getting a class blessing without any references to "previous failures" or whatever. So come she does not have a class? Or why no one is saying something like "oh, he is also classless like his sister"? Or is this a world where older sisters are actually younger than their brothers?
And of course the initial "rival" for the MC is a tomboy, that pretends to be a boy, but later will become a hot girl, reveal it as something "were you stupid and did not realize I was always a girl?". And become a love interest. And love rival with MC's sister, I guess. The three of them will train and train and train and train and train and train and train again, through-out the nights even, realizing at some point, that anyone can actually learn any skill, if one works hard enough and has friends.
Not a good hook for me.
