9th Elementary Anti-Alien Squad

9th Elementary Anti-Alien Squad is the first episode of the Alien 9 anime.

Plot
A new year starts at Division 9 Elementary School and each class begins handing out duties. Amongst the usual roles like class president, however, there is one that is rather unique: Alien Fighter. Yuri is in her final year of school and is shocked to find out that she has been elected to join the Alien Party. This is her worst nightmare, because she hates aliens. Her worst fears are realized as she attends the first meeting and learns that not only must she catch any aliens that attack the school but also wear an alien on her head! This is known as a "borg", a parasite creature who depends on the host. Each member of the Alien Party is given a borg, which have wings for defense and the power to attack others by extending long and flexible drills. The other members of the party are smart, confident Kumi and Kasumi, who seems to be good at everything she puts her mind to. Both volunteered to join the Alien Party, but Yuri doesn't know why. There's not much time to chat as the trio are sent out with nets and rollerblades to skate after the latest alien running around the school. Yuri struggles to deal with her responsibilities and looks to others for help, but with nowhere to turn she must keep on regardless. As new threats appear at the school, Yuri, Kumi, and Kasumi must learn to work together to fight the alien invasion. But is their Alien Party Advisor telling them everything they need to know?
