Koi-ken! Watashitachi Anime ni Nacchatta! (Literally, Koi-ken! We’ve been animated!) is very loosely based on the Koi-ken! dating sim games. In the games, the Renai Kenkyuukai (Love Research Club), or Koi-ken for short, does research into love. In the anime, the girls of the group end up forming an idol unit with Nagisa Toyama (a member who was already an idol) and have a concert.
This originally aired as twelve mobile phone ONAs of four minutes each. The Bluray release turns it into one OVA, 53 minutes long. (There are chapter marks for where the episodes fell, but it plays as one long story instead of being broken up.) There’s a total of five songs, three of them full length. (It’s actually six if you count the end, but the end is just a shorter version of the fourth insert song.)
This is uncensored, so you get some nudity and nipples. Don’t say we didn’t warn you. ( ¬‿¬)
We’ve also released the OST for this on CMSSide, so check that out too!
