Boku wa Tomodachi ga Sukunai Plus (僕は友達が少ない+), or shortened as Haganai + is a manga series authored by Misaki Harukawa and illustrated by Shouichi Taguchi. The series ended with 2 volumes which were published between November 2010 until June 2012. It was serialized in Jump SQ. 19.
Unlike the other iterations of the series, Haganai + takes on a "what if" scenario in the story's plot, where characters get acquainted in a different manner than they did in the original light novel series.
One day, he stumbles on the school's most popular student, Sena Kashiwazaki talking to a game novel character - Renka. After a short discussion, Sena agrees to try making real friends alongside Kodaka, who established the Neighbor's Club for the latter purpose.
