EmmaKasu is the femslash ship between Emma Verde and Kasumi Nakasu from the Love Live! fandom.

Love Live! School Idol Festival ALL STARS
Emma and Kasumi are the members of the "Nijigasaki High School Idol Club", however due to misunderstandings of the members with the former club's leader Setsuna Yuki, the club was fractured by their leader itself during the group's break, with Emma (who flew back to Switzerland), Shizuku and Kanata were all split up from the club, leaving Kasumi the only remaining member. By the time the player formally joins the club with Kasumi's help to restore the club back, Emma has just arrived from her home country and Kasumi was really worried about her. Over the course of the story, the two eventually get along from time to time.

Love Live! Nijigasaki High School Idol Club
Sometime before the show takes place, Emma and Kasumi, along with Kanata and Shizuku, were used to be the original members of the "Nijigasaki High School Idol Club" founded by Setsuna Yuki, however due to its members were unable to keep up with Setsuna, especially for Kasumi who was hit hard by her passion into idol, the club was outright disbanded during the group's break just ahead of the debut concert at DiverCity. In spite of being former members of the group, the two rarely get much interations even after the club being re-established again, although they made a small conversations at some point of the story.

In preparation for the 2nd School Idol Festival, Nijigasaki is inviting several schools for the joint concert. with Jennifer and Rakshata from Y.G. International School being the first to volunteer because Emma knew about them. Their conversation went normally, however when they talked about Lanzhu's concert from the other day and why she isn't part of the club yet, Kasumi snapped out of jealousy at Lanzhu's performance. While everyone's making conversastions, Emma began worrying for Lanzhu because she knew they were both transferred student to become a school idol, so she want to ask her to which surprises Kasumi and went out to assist her. The plan didn't go well when Lanzhu immediately declined and walked way from them. The pairs end up walking together around the campus (one which takes place just outside the main building) and meet up again in front of the entrance after their class session.

After the success of Nijigasaki's "First Live with YOU" major concert, Kasumi was requesting an antique chair for their club room, but Shioriko, who was now the new student council president, declined her request. Emma however comforts Kasumi by patting her head and told her she was pretty sure if Setsuna was still the student council president she would decline too.

Fanon
EmmaKasu ship was one of few less popular ships among the Love Live and Nijigasaki fandom largely due to being overshadowed by other popular ships and having less interactions and presence throughout the media, however the ship gained minor vocals among some handful fans and worshippers due to their purity, innocently, and the cuteness overload with their voices and their appearances being the only two members in the group to have those traits.

This ship forms a mutual ship with KanaRina being part of the subunit QU4RTZ and also friendly with fellow less popular ships such as EmmaShizu, however this ship is primarily rivaled by other popular ships with ShizuKasu and EmmaKari, as well as forming mutual rivals with EmmaRina, KanaKasu, KasuRina, and KanaEmma.
