Yukaeso

 is the femslash ship between Yuka Jennifer Sasago and Esora Shimizu from the D4DJ fandom.

Canon
Yuka and Esora are both members of the DJ unit Peaky P-key, as well as first-year students at Yoba Academy (although it is not known whether they are classmates). Yuka is the unit's VJ, while Esora serves as Peaky P-key's background vocals, second dancer and as the self-proclaimed "lovely" member. They both have energetic and friendly personalities, though they have their differences as well. Although Yuka regards to everyone in Peaky P-key as her best friends, she and Esora are particularly close. The two have known each other since middle school, when Peaky P-key was formed.

In Yuka's initial 3* card story, titled "The Picture of Friendship", Yuka is shown taking pictures at the local nature park, before Esora runs after her and scolds her for leaving her while she wasn't looking. Yuka apologizes before showing Esora the pictures she just took of a wild bird, who then compliments on how perfect they are. Yuka thanks her, but also says that she screwed up the timing a bit so it's not that perfect in the end. Esora giggles and compliments Yuka on how cool and clever she looks while photographing, which leads to Yuka speaking in broken English, and Esora groaning how she's "returned back to her normal self now". Yuka tells Esora that she's going to move to a different spot now, and the latter joins her, saying that "just watching you taking pictures is so much fun, too". As the two hang out for a while, Esora and Yuka notice two children fighting. Esora ponders if they should do something about it, before Yuka rushes over to them and helps them resolve their fight. After the girls leave, Esora approaches Yuka and tells her she did a good job, and Yuka retaliates that Esora should've helped her out instead of just watching, but Esora insists that her "lovely charm isn't suited for helping kids". Yuka then shows Esora the pictures she took of the children having fun and playing with a wild cat and says she's completely content with how the pictures turned out.

In Esora's New Year's 3* card story, titled "Cruising the Skies on New Year's Eve", the Peaky P-key members are sitting in a ferris wheel owned by Esora's family. As they reach a certain height, Yuka asks if they can stop it for a second so she can take a picture, and Esora asks the staff to do so. Yuka takes so many pictures that she uses half of the camera's film just during that moment. They proceed to continue the trip, after which Esora surprises her unit members with toshikoshi soba noodles and fireworks, the latter making Yuka blush. Esora explains how she perfectly timed their trip with a New Year's event that was being hosted in the park below then, and Yuka compliments her, before taking more pictures. The story ends with Esora happily thinking how she's going to make a wish, but decides that she'll make it during the unit's first shrine visit instead.

Fanon
Yukaeso is both Yuka and Esora's most popular ship. It is currently the 5th most written ship in both the D4DJ Groovy Mix and D4DJ First Mix tags on AO3. Despite this it is not as widely shipped as Peaky P-key's other "main ship", Kyoshino, and is even regarded as a rarepair, especially in the Western side of the fandom. This is also due to D4DJ not being such a popular or well-known series yet.

One way or another, this ship is obviously considered the main one for both characters for a number of reasons (D4DJ and other similar franchises are based on strong emotional bonds and deep interactions between character pairs), so even when the girls are expected to expand their range of interactions with the expansion of the lore franchise, they will most likely get most of the shippy moments with each other.

Trivia

 * In a live interaction between the two and Shinobu, Esora starts panting and groaning how she's about to reach her limit (due to her limited stamina), after which Yuka tells her that they're going to have a proper training session together.
 * In another live interaction between the two, Yuka yells "Raise your hands" but mispronounces it, before Esora corrects her with the proper pronunciation.
 * In the Hello DJ - Halloween Live! event, for Peaky P-key's Halloween performance, Esora dresses up as a nurse, while Yuka dresses up as a mummy. Kyoko comments that they look cool and like they're matching.
 * In Esora's birthday area conversation, Yuka's "priceless" gift for Esora is holding her in a bridal carry.
