The characters from both Haganai and Seitokai no Ichizon visit each others' clubroom in this two-part crossover. Strangely enough, the male protagonists from each manga do not make appearances.

Chapter One:
The Neighbor's Club gets a mysterious message from a certain student council! This chapter was drawn by Itachi, the artist of the Haganai manga.

Chapter Two:
The Hekiyou Gakuen student council receives an invitation from the Neighbor's Club to visit. This chapter was drawn by 10mo, the artist of the Seitokai no Ichizon manga.
