Jyuzaengi Engetsu Sangokuden - 1 episode
The Juuzas are the cat people or the 13th Zodiacs. After participating in a war, they now live in a secluded place. The story looks like it started in the middle of something. There's a lot of characters introduced that you can't distinguish who's the villains and comrades. I'm very confused with the story that I can't even construct a proper synopsis. It's just damn too short and fast-paced. By far the most uninteresting reverse harem OVA compared to other otome adaptations that didn't get a full series like Kuro to Kin and Hanayaka Nari. I think it helped that they were given a second episode and but in Jyuza, they have to compress everything in 30 minutes. I can see the potential if this was a full anime series. You may try to play the otome if you want to give it a chance.
If you're familiar with the Dynasty Warriors characters, then you'll see them as bishies reverse-harem style. The only hint of reverse harem and romance is the opening credits. That's it. The only cute factor too is Liu Bei's very hot transformation.
