An adorable, sweet and fluffy shounen-ai that had me smiling throughout. It is a very short manga, but Kanada sensei still manages quite a bit of character development, particularly with Koujirou (I loved seeing him open up as he notices Lau's attention). The premise and plot are not particularly original, but the execution is clever and uniquely Kanda-sensei -esque.
That aside, I think the goal of this manga was comedy, and that goal was definitely achieved.
The interactions between the protagonists were adorable in their innocence and light-heartedness, and the side characters added an extra funny element to the story.
My one qualm: It is not clear to me at all whether its easier for the characters to be in their human form or their Kago form. One of the side characters keeps forgetting to hide his horns, and Lau had more trouble than usual keeping his human form when his Kago powers got particularly strong. But when Lau stays in his Kago form for several days, he exhausts himself. This is very confusing (it's not a particularly important issue, and itdidn''t detract from my enjoyment, but I do like it when a universe is internally consistent).
