It was dumb, it wasn't any continuation of the main story or anything vital to the story line. Just a little edo era themed episode that puts our characters in a different environment.
It was funny though, and very cute, so yea...I liked it lol
For anyone who doesn't know or understand what an OVA is, it is essentially a reimagining or a new story with the characters from another anime. It is made by the original creators just for fun or to practice animation, sometimes these get released.
My Little Monster OVA was very funny and light-hearted. I would probably watch it if it were made in to a multi-episode anime. I wouldn't necessarily say it is an improvement on the original anime, but I also wouldn't say it is worse. They are about equal in quality. If you have seen the original, I would recommend this for a laugh.
It's a funny OVA haha! At the end I was like: what the actual f- But it was worth watching xD
Spoiler: The fact that even in this OVA Kenji was lost again is too funny lmao. And finally, Haru and Shizukui kissed ^^
awesome story way better then the anime. wtf was that ending!!!!!!!!!!
