Here is the List of Nisekoi Volumes that have been published by Shueisha in the weekly magazine Weekly Shōnen Jump since November 2011. The individual chapters have been gathered in a tankōbon volume and each volume title has been based on one of the chapter titles of the series. Also, every volume and chapter title has been written in katakana. Although a chapter title holds kanji meaning, it would still be written in katakana.
In North America, two volumes of this manga series have already been published by Viz Media with the name being Nisekoi: False Love. Nisekoi can be translated as "False Love" and thus the manga will explain the meaning behind that name.
