This invention is a device which Lala uses in order to seemingly lose memories that people retain about anything regarding to the user.

Appearance
It appears in the chapter 48 of To LOVE-Ru, when Lala uses it for deleting the any memories of the people on the Earth (because she want start a real relathionship with Rito without he knowing about her being a princess or him being her fiance) and it ends up in a failing plan. Although this device is turned on, Rito, Haruna and their friends don't get affected by it, but Zastin gets affected and he temporaily forgets his own name.

In anime, it debuts and only appears in the episode 26 of first anime. Despite the main plot to be different from the manga, even in this case Lala uses it in an attempt to forget any memories of people about her. She transferred back to Sainan High School not long after but, as in manga, everyone still had memories of her and joins together with Lala in the classroom. Its the last invention that appear in the first anime.
