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 two volumes which were published by Shueisha 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.
