Unnecessary Chocloate is a 3-page special chapter for the To Love-Ru manga, contributing for Valentine's Day.
Rito and Saruyama talk about Valentine's Day, which gets Rito to daydream about Lala, Haruna, Yami, and Yui in extremely lewd wear and saying "eat us." This causes an extreme blush from Rito. Saruyama only wants chocolate from Riko, which Rito immediately says that it will never happen.
This special appears between Chapters 135 and 136.
