I don't know how to recall it but when I watching this OVA I didn't feel "I am watching an anime" but it was like "I watching a bad but bizarrely watchable theater!" I don't recommend this to everyone (cause I can't explain why I didn't feel exhaust after it!) but my reason to putting it in mixed was after play the anime and passing time I realize I watched a couple 40 mins long episode without a proper story, or some interesting characters... I surely follow story as time past but this no plot anime make me sit and watch it whole 2 ep maybethe end of it was interesting for me! I don't sure about that!
