Nisekoi is a romantic comedy that follows a couple that are only pretending to be together for the sake of their respective yakuza families. In order to keep the peace between the gangs, Raku Ichigo and Chitobe Kirisaki must pretend that they are a couple. Raku Ichigo has a locket that was given to him by his chidhood sweetheart, and he is determined to find the woman who has the key. He has feelings for his classmate, Kosaki Onodera, and hopes that she is the one who holds the key to the locket. Problems arise, however, when he discovers that there are many keys that fit the locket, and searching for the right girl becomes a bit of a nightmare (albeit hilarious) quest.
