Little Busters’ Rin Natsume wallpaper, click image for full size (1920×1080).
Little Busters started as a visual novel in 2007 with a harem theme. It’s about a high school kid and his friends, with Rin as the main heroine.
It’s one of the best selling video games in Japan during its release period. It expanded into manga and anime series later on.
BTW it’s not uncommon for a video game to turn into an anime. Beside Litbus there are also Clannad, Idolmaster and Fate/Stay Night etc.
