Ah yes, this series has been updated sporadically for weeks and ended (translation wise) months ago. So the unique feature of this series lies in the utilization of "mystery." This title has managed to make it work in a way that is better than other series. That being said, sadly that is the only edge here as everything else is just.....subpar. Hyoujou Ga Issai is overly reliant on tropes and the Ecchi scale, there is no balance as it's tipping excessively in one direction. While I understand the appeal of using Ecchi, using it too much will bore people. It also doesn't help that the story isn't exciting,it's just the usual antics most of us are familiar with.

Am I surprised it ended early? Not really, I'm sure anyone can sort of see how this story can't last for the long term.
Let's just be glad it ended and acknowledge it was an okay read.
