Nisekoi

Nisekoi follows high school students Raku Ichijo, the son of a leader in the Yakuza faction Shuei-gumi, and Chitoge Kirisaki, the daughter of a boss in a rival gang known as Beehive. They unexpectedly meet when Chitoge hops a wall and kicks Raku in the face. After she runs off, Raku realizes he has lost his locket which was given to him by his childhood sweetheart with whom he made a secret promise. After discovering Chitoge is a new transfer student in his class, he forces her to help him look for the locket. During the search, they begin to despise each other with a passion.

Upon returning home, Raku learns that the Shuei-gumi and Beehive gangs have agreed to settle their feud by pairing their leaders' children. Much to his horror, he learns that his girlfriend-to-be is only Chitoge. For the next three years, they must pretend to be in a relationship to maintain peace between the gangs. This turns out to be quite a challenging task, not only because of their hatred for one another, but also because Raku has a crush on another schoolmate, Kosaki Onodera, whom he secretly wishes was the girl who bears the key to his locket.

Nisekoi was listed at number 30 out of Oricon's top 30 manga series sold in 2013, with 1,542,417 copies sold. In 2014, it was ranked 16 out of top 30 manga series sold in 2014, with 3,816,372 which is more than twice the sale of 2013. As of April 2018, the manga had 12 million copies in print.

Rebecca Silverman of Anime News Network writes that the Nisekoi manga has a large lack of originality, such as "nearly every plot point can be traced back to another shōnen series (primarily Sumomomo, Momomo in terms of Raku's home life)". She also mentioned that "seasoned readers of shounen romance will recognize elements from at least three other series in there." However, Silvermon enjoyed the art and overall sense of fun.
