Promise (ヤクソク, Yakusoku) is the last chapter of the Nisekoi manga series written and illustrated by Naoshi Komi, published weekly in the magazine Weekly Shōnen Jump.

Summary
Several years have passed since the events from the last chapter. Raku has achieved his ambition of being a government worker in the department of public safety at Bonyari City Hall, however he is also the head of the yakuza faction after his father, while Claude has become the next head of the Bee Hive Gang and is on good terms with Raku himself. Raku then sees his father off as he heads on to his retirement honeymoon with Raku's mother together.

Raku then calls Shū, his friend and wedding organizer, if he received an invitation to his wedding. It is shown that Shū and Ruri are in a relationship and are handling their finances in order to get married like Raku. Afterwards, Shū calls their former teacher if her invitation arrived too. Kyoko is expectant about the wedding and wants her former students to meet her two children. At the same time, Fuu and Haru also talk about the marriage as Fuu shows the article she wrote about Onodera's sweet shop. Haru laments the fact that she has not yet found a suitable partner for herself and joke about how they believed Paula wouldn't graduate but ended up working in a lab. Raku also contacted Yui who is expecting a child and reports that she is looking forward to seeing everyone. Tsugumi, who became Chitoge's personal model for her designs, is also called up to attend the wedding. At the same time after receiving the invitation, Marika tells Honda that she'll be attending her blind date in order to find a better man than Raku. Meanwhile, Kosaki is seen talking to the phone with Raku about attending the wedding and baking a grand wedding cake for his ceremony.

Later that day, Raku meets up with an impatient Chitoge at the field where the special promise had occurred. Both reminisce on the events of their busy lives and the burial of the locket and keys to end the special promise made several years ago. As the two bring along a new locket and key to symbolize their love for one another, Raku re-asks Chitoge to marry him in which she replies to with a yes. They reflect on their journey, making jokes about it before Raku starts to head off to let Chitoge to her business. Chitoge stops him by asking Raku to give her a kiss, their first kiss as a couple. The two are nervous at first, but in the end they share a kiss but end up hitting teeth and arguing as usual.
