Boku wa Tomodachi ga Sukunai lit. I Have Few Friends), also known as Haganai (はがない) is a Japanese light novel series written by Yomi Hirasaka, illustrated by Buriki, and published by Media Factory. It involves the story of Kodaka Hasegawa, a transfer student to St. Chronica's Academy. As with every other school he has ever attended, he finds it difficult to make friends there because of his naturally-blond hair (inherited from his deceased English mother) and fierce-looking eyes, which make him look threatening to his prejudiced schoolmates.

One day, Kodaka accidentally comes across the equally solitary and very abrasive Yozora Mikazuki while she converses with her imaginary friend Tomo. Realizing that neither of them have any social lives, they decide that the best way to improve their situation is to form a club – the Neighbor's Club (隣人部 Rinjin-bu)– with the intention of making friends and learning social skills.
