Multiplication ~From the Front and From Behind~ is a bonus chapter released after Chapter 77 of the To LOVE-Ru Darkness manga. The chapter begins with Lala inventing something in her room. Mikan asks her to take a bath but sees her inventing something special. The next day at school, Nemesis uses the Principal as a chair and is shown reading a magazine when Yui and Nana show up. Yui forbids Nemesis for such violations, but Nemesis says that he is enjoying being a chair. Meanwhile, Yami and Mea show up eating taiyaki and lollipops. Mea says to Nemesis that she is a student at the school now so she should be responsible. After a small conversation they begin to fight for a warm up exercise because they believe that they will get weak if they don't exercise. Yui and Nana beg them to stop fighting in the school grounds as it's a violation of school morals. Meanwhile, Haruna is carrying some books and Rito helps her. Haruna is happy that Rito helped her and says that he is kind. While talking they are interrupted when Lala arrives and shows her invention named Nyan Nyan Copy-Kun, a cat robot that can make a clone of anything that touches it. Haruna then accidentally trips over Rito's leg making him to fell onto Lala' chest and the robot receiving an electric shock. Rito then sneezes getting a clone of himself. The two Ritos then fall on Sairenji in a suggestive pose.
