EmmaKasu

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 because of 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 for her. Over the course of the story, the two eventually get along from time to time.

Love Live! Nijigasaki High School Idol Club
Emma Verde is a third year student and Kasumi is first year student of Nijigasaki High. Prior at the beginning of the series, they were the former members of the original School Idol Club founded by the school idol Setsuna Yuki, with Emma being one of the first member to join and Kasumi was the last one to join. However due to members unable to keep up with Setsuna’s dancing skills, the club was the disbandment before its debut concert. A few days later, Kasumi wants to revive the club with the help of second year students Yu and Ayumu and gathered everyone and the former members to talk about how to bring Setsuna back to the club, from which they succeeded. Emma and Kasumi declared the school idol club is officially back and restarted again.

Throughout the club activities, Emma and Kasumi began forming their relationship slowly from their small talks and interactions like asking if Rina is really in the apartment and discussing where to hold their School Idol Festival. Emma is seemingly attracting to Kasumi’s charm and her fondness to anything about cuteness. Their bond has finally formed when Emma and Kasumi began training together for the upcoming joint concert after failing to convince Lanzhu to join the club, leading Emma to form a subunit in attempt to prove Lanzhu that school idols need a connection with fellow members and their fans. After their consecutive concerts, Emma and Kasumi can occasionally seen standing or sitting next to each other, and even challenge in a card game, implying their strong friendship since the club has re-established.

At the special event organized by the School Idol Club, Emma and Kasumi’s relationship reached the cumulative part when they made a group hug after their Subunit succeeds their solo part. Right before the final part, Emma convinced Kasumi to smack her back and likely returned to ease up the tension ahead of the last performance. After a successful concert, Emma and Kasumi has finally sailed when they have a small talk about the ancient chair that Kasumi wants to bring it to the club but the new student council president Shioriko rejects her offer. Emma then headpat Kasumi’s head to comfort her and told her if Setsuna was the president then, she’d also reject her chair too. Kasumi wasn’t amused.

Fanon
EmmaKasu is one of the least popular Nijigasaki ships in the canon and within the Love Live fandom. While they're technically part of QU4RTZ subunit, Emma and Kasumi however rarely interact in the series aside from their few moments in the story and in selected songs. Even if the staffs seemingly teased them in some part of the story such as Emma and Kasumi's sprites appears holding hands in the mobile game School Idol Festival ALL STARS and sharing their moment in the final scene of the anime series' 2nd Season, the ship's popularity remains largely unchanged. Despite the status of this ship, certain fans has found potential of this ship primarily because of unique traits and charms they have primarily their cute voices, their green/yellow contrast of image colors, their relatively height and size difference, and oddly to extend, their matching hair colors. It is said that Emma and Kasumi shares the same vocals when they make a duet in selected songs.

EmmaKasu forms a mutual friendship with KanaRina and other least popular Nijigasaki pairs, however it is heavily rivaled by popular ships such as ShizuKasu and EmmaKarin, and it's being contested with mutual ships KanaKasu and EmmaRina.
