This ''anime'' seems to be more like a promotion (i pretty sure it is) for the manga. Each episode is only 1min long and at the end, you see the volumes of the serie. Each episode seems to be a summation of one of the volumes available.
Since the episodes are only a promotion for the manga, there is no depth story in the episodes, it's all surface, all summation. If you are interested, just go read the manga!
The art is pretty good, very sweet and bubbly.
Lots of background music, dynamic (well it's a promotion, so it makes sense)
Again if you
want to get to know the character more in depth, the manga is for you.
Only 4 episode of 1min each, It only takes few minutes to watch. Not too bad, I didn't feel like it was wasting my time, but it sure made me want to read the manga (resulting on me adding it to my plan to read list)
If you are not sure about the manga, I recommend watching the first OVA, with the same title but was made in 2014. The episode is 15min or so, and it gives you a before-taste of the serie and how the characters are.
