The official site for The 100 Girlfriends Who Really, Really, Really, Really, Really Love You anime released the main video for season 2 on Sunday. It shows the new heroines' voices and previews the opening song. The heroines from both seasons, voiced by their cast, join as "Rentarō Family" to sing the opening "Arigato, Daisuki ni Natte Kurete" (Thanks for Being So Lovable). The song's CD, with the season's ending theme, comes out on February 5.
