Synopsis
Nisekoi centers around Raku Ichijou, a high school student with a secret: he's the son of a yakuza boss.
He's mostly uninterested in that life and more interested in his crush, Kosaki Onodera.
However, his life is turned upside down when he's forced into a fake relationship with Chitoge Kirisaki, the daughter of a rival gang's leader, to prevent a gang war.
Despite their mutual dislike, they must pretend to be in love.
As Raku navigates this forced romance, he also continues his search for a girl from his childhood who holds the key to a pendant he owns, a promise from years ago.
The story follows their comedic and complicated interactions, with new girls appearing who all seem connected to his past.
