Infinite Stratos 2: World Purge-hen (2014)

[IS 〈インフィニット・ストラトス〉 2:分離解体の世界たち（ワールド・パージ）]

Director: Yatsuhito Kikuchi
Studio: Eight Bit
Starring: Koki Uchiyama, Yoko Hikasa, Yukana
Episodes: 1

Synopsis:
While Ichika is away, the Academy falls under cyberattack and the girls take the risky option of fending off the hackers in virtual space.

Impressions:
This OAV primarily serves as an excuse to see the girls' lewd fantasies play out. It's mostly self-contained, but some of the plotting behind the scenes could be setting up the next arc of the story which we're not likely to ever see animated. Besides the aforementioned lewdness, we do get to see Chifuyu in action against some SF operators launching a physical invasion at the same time as the cyberattack, so that's neat. Still, the main reason for watching this is the fanservice, which may not be reason enough for you. Take it or leave it.

Rating:
50/50
