Rooming with a Gamer Gal(2014)

Yuube wa Otanoshimi Deshita ne

Takumi Satsuki (Early 20s, Male - Female in-game) became friends with Goro-san (Male) on Dragon Quest X, and they decide to become roommates. When he goes to meet up with Goro-san though, who he finds standing there is someone who doesn't resemble their character in game one bit--a gyaru...?! This unintentionally catfished couple has a lot in store for them in this fun romantic comedy!
