The story is bizarre with little backstory but since no story goes very deep, it is not an issue.
Each episode has a stand alone issue which Wakasa (Free loading Merman) and Tatsumi (Teen whose bathtub has been taken over) both overcome usually in a pretty adorable way.
I love the voice actors chosen, they are absolutely perfect for the characters, especially Maki, his voice made me giggle at times XD
The artwork is not super detailed but personally I think it is fantastic, it suits the light-hearted theme and the chibi forms of each character are adorable.
To me, this is short episodes done right, I cannot say I have extensive experience of shorts like this, but a few of the ones I did encounter cut corners with the artwork, some things had a lot of detail but the backgrounds were just dragging the whole thing down and then the story seemed rushed, but with this, nothing seemed rushed.
If you like light-hearted comedy and adorable characters, then I will be surprised if you do not enjoy it. I recommend giving it a try since the episodes are so short, no time wasted even if you find it is not for you.
