Soon after entering middle school, Yuri Otani is coerced into joining the "Alien Party," a single-minded group with one goal: capture any alien attempting to enter school grounds. Terrified of aliens her entire life, Otani is anything but thrilled, and to make matters worse, her kit includes a "Borg"—an alien-like creature tasked with ensuring her safety. Despite this, she finds solace in her two partners: the independent and reliable Kumi Kawamura, and the smart and energetic Kasumi Tomine.

As the Alien Party works to fend off extraterrestrial threats, will their roller blades and lacrosse sticks be enough to overcome the dire challenges ahead, or will they succumb to fear and suffer the grim consequences of defeat?

Alien 9 is one of those hidden gems you find every now and then with anime. It just barely catches your eye, so you pick it up, dust it off, and find an incredible piece of work that has, somehow, against all odds, remained in relative obscurity, languishing with a mediocre reception. I stumbled upon it by total accident as I was looking for a quick watch, and armed with nothing but a brief description I settled in for what I thought was going to be a fun yet average experience. I couldn't have been more wrong. Instead, I got Madoka before Madoka. I got ...

Mixed Feelings
Alien 9 is about three girls beating up aliens. One of them hates the job, one of them does it because the other option was worse, and one of them is raring to go. There's a copious amount of gore, blood, and mental breakdowns. So yeah, this show is not all sunshine and lollipops.

From the first scene, Yuri (the first girl I talked about) will whine about not wanting to be the one designated to beat up aliens in her class. In the next scene she will complain and whine to her best friend about how she's unqualified for the job, and that she doesn't ...

Wasted potential.

I’m sorry, but I just don’t think this anime explained its main plot elements nearly well enough to warrant a higher rating, which is a real shame since I was hoping this would be a potential 7/10 or 8/10 upon seeing the second episode. So many questions are left unanswered, and the sheer amount of completely wasted time (all of episode 3, A.K.A. a full quarter of the runtime) in an already short series was infuriating beyond belief.

This OVA started off with amazing potential in the first two episodes, before completely throwing it away for a filler-like third episode which was so desperately ...
