First episode: ooh, a sport anime!
Second episode: slice of life
.........
and then, when you reached a few more episodes later, you might come to the realization that this, in fact, isn't another classical sport anime like Kuroko no Basket.
If you're looking for hardcore sports from the beginning to end, you might have to give this up because Keppeki Danshi, even though gripping and epic, is simply not completely soccer-filled. It's more biased toward slice of life than sports in general. If anything, I would say that it's slice of life involving soccer rather than soccer with small slice-of-life moments.
But if you're looking for simply another sport anime, funny (wtf) moments, fan-service, (one-sided romance), dude team-bonding, (gay-shippings), and OP character, look no further because this anime gives you all that.
This anime, for me, was a pretty decent one, but would have been better if they'd made it longer (wouldn't it be better if they made all anime longer?!!). Anyway, I think this anime will, probably, worth your time so give it a shot!
