25th and last manga volume released in January by Viz Media
Chitoge, I mean Nisekoi fans rejoice as the 20th issue of Weekly Shonen Jump has announced that Naoshi Komi's Nisekoi manga will be getting a live-action film adaptation slated to be released this December in Japan. Viz Media describes the manga:
It’s hate at first sight—or rather a knee to the head at first sight —when Raku Ichijo meets Chitoge Kirisaki! Unfortunately, Raku’s gangster father arranges a false love match between Raku and their rival gang leader’s daughter, who just so happens to be Chitoge! Raku’s searching for his childhood sweetheart from ten years ago, however, with a pendant around his neck as a memento...but he can't even remember the girl’s name or face!
Aniplex of America released both seasons of the anime adaptation on home video, which are also available streaming on Crunchyroll and linked above. It's a really fun series, once you realize who best girl really is.
