I thought the main series was just alright. I generally watch any extra OVA episodes if that's the case. If you feel the same, I would advise skipping this. It's a double-length episode and Part A is built around extremely racist jokes. Like. EXTREMELY. Like. Literal slave shit and rape terror shit. It's not worth it. And, like, this is the anime community, so I know there are going to be people who say it "wasn't that bad" because it was "short" or whatever. No. Fuck that. It was extremely uncomfortable and entirely unnecessary. Enough that I would reiterate that if you weren't completely sold onthe main series, this adds nothing and isn't worth it.

Part B isn't funny, but two of the girls go very OOC to have sex under a futon. It's really nothing special and in no way makes up for Part A.

Black Lives Matter. Fuck this OVA.

Edit for the other review: "...isn't this just definition of Japanese xenophobic culture?" is a deeply ignorant thing to say about Japan. It's not OK to be xenophobic. There is no monolith in Japan that says it's OK to be racist. There are Black Japanese people. Japanese media does not get graded on a curve with regards to diversity. 2013 is not "another time." The fact that the only Black men who appear in this series appear like this is racist on its own. The fact that you did not *recognize* those drawings of Black men as drawings of slaves or the joke being the threat of violation that they posed to a vulnerable girl speaks volumes... about you and your lack of awareness. Fortunately, your extremely *forgiving* description is enough that literally anyone with their head screwed on right will understand what I was talking about. Wait a few years and ask yourself why you felt the need to go to bat for this shit like you were somehow defending Japan. Embarrassing weebery.
