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 a bizarre and sadly very much underrated coming of age story. It is set in a school which suffers from constant daily alien attacks. Most of the aliens are best-like creatures both in mind and body. Our protagonists are three 12 year old school girls who were in one way or another recruited in the Alien control party.

The basic look and premise of the show do not appear to be special from the first glance, yet mere minutes are enough to see that you are into something much more than just another high-school, moe, action anime. There are a few things ...

Mixed Feelings
A decade before Madoka Magica subverted tropes of the magical girl genre and spawned a new wave of “darker” magical girl shows, Alien 9 did something a similar vein. Starting off as a quirky sci-fi slice-of-life featuring cute girls fighting aliens, this 4 episode OVA lulls you into thinking it’s a fun little sci-fi adventure romp with its unassuming first episode, and then proceeds to shatter those expectations throughout it’s the rest relatively short run-time. It’s a bizarrely off-kilter yet compelling mixture of quaintness and horror that puts a uniquely sadistic twist on common anime tropes, even by today’s standards. Unfortunately, we’re ultimately provided with ...

At first glance, Alien 9 appears to be a cute little anime about chasing aliens on roller blades. Thinking this was the case, I bought it. I thought that they must have been exaggerating or in complete error when I saw the 13+ rating. Not. Despite its cheery and cutesy character design, this is a very dark and disturbing anime.

I should have known something was up when I kept getting bad feelings for no reason. Things happened in the anime that made zero sense, and yet I felt completely horrible while and after watching it. When I finished the series (4 30-minute episodes), I couldn't ...
