Little Sister

Little Sister (イモウト, Imouto) is the seventy sixth chapter of the Nisekoi manga series written and illustrated by Naoshi Komi, published weekly in the magazine Weekly Shōnen Jump.

Summary
Haru declares that she is Kosaki's sister. In a flashback, we see Haru overhear Kosaki talking on the phone, insinuating that she has a crush on "Ichijou-kun". Afterwards, Haru gets on the phone with her friend and hears about how there is a terrible Yakuza gang boy named Ichjiou.

Back in the present, Haru believes that Kosaki has been tricked by Raku, and warns Raku to stay away from her sister. Chitoge comes by and asks who the new girl is. Chitoge learns that Haru is Kosaki's sister. As Chitoge approaches Haru, Haru asks why Chitoge is with a guy like Raku, since she is so pretty and he's such a bad guy. This makes Chitoge take a liking to Haru immediately.

At this point, Marika comes and pounces on Raku, asking him to dump Chitoge and become her boyfriend. Haru asks why she's going after someone with a girlfriend, and Marika explains that true love can overcome any obstacle. Kosaki tells Haru that Raku isn't such a bad guy, which retorts to Haru saying that Raku saw her panties.This causes Chitoge to punch him.

After, Haru leaves and looks at clubs. She wants to join the caretaking club, but is dismayed when she sees Raku is part of the caretaking club. As she leaves, she overhears Raku wish Kosaki was there. She declares that he is terrible, and that she'll never let him have Kosaki. As she points at him, a swan flips her skirt again, and he sees her panties a second time. Haru slaps Raku again.

Later that night, Haru takes a bath with Kosaki. Kosaki insists that Raku is a good person and says that Raku is selfless, and always thinks about other people. Haru tells Kosaki about her prince. After the bath, Haru remembers that she has a strong lead on who her prince is, and reveals that she has Raku's pendant. In the final panel, we see  Tsugumi  surprised to find  Paula  attending  Bonyari High School.
