I guess this is supposed to be an alternative version of the 2014 adaptation of Jutaijima. It has the lady-doctor from the original Jutaijima, along with three new girls. One of them is a gyaru. I guess that's cool...?
In O.G. Jutaijima everyone looks like they've been dumped in a vat of baby oil. The director must've taken that aesthetic choice to heart, because he decided to wholly embrace the baby-oil aesthetic for a second time, which is fine by me. However, O.G. Jutaijima doesn't have characters with pug-fugly potato faces, so his decision to include that in this version is questionable.
TL;DR: Uhh... it's an alternative version of Jutaijima that looks slightly uglier than the original, which isn't saying much. I don't think anyone really wanted or needed this.
