Hayakoko

Hayakoko is the femslash ship between Hayate Tendou and Kokoa Shinomiya from the D4DJ fandom.

Canon
Hayate and Kokoa are both first-year students at Arisugawa Academy as well as members of UniChØrd. In their biographies, it is mentioned that the two met for the first time in middle school. Feeling isolated due to her family circumstances, Hayate found Kokoa's music and resonated with it. After that, she tried her hand at poetry, and ended up discovering her talent for writing lyrics. The two then decided to team up together, and their relationship started progressing to the point where they started dating.

They have opposite personalities: Kokoa, despite her outwardly cheerful appearance and image of an honor student at school, is in reality quite cheeky and cocky. Meanwhile, in contrast to her cool appearance, Hayate is quite carefree and sometimes does things that catch others off-guard, but she is also deeply observant of her surroundings at the same time. As such, she is able to tell Kokoa that she deeply loves her without batting an eye.

The two are first shown competing as a duo unit, Haya-Coco, against Michiru at FROLIC, where they end up losing against the latter. They talk a bit with Michiru after the battle and then bid their farewell. Upon arriving to the dressing room, Kokoa completely explodes and starts ranting about how sore she is feeling, and how there's no way her and Hayate's unit could lose in any circumstances. When Kokoa is done, she apologizes and says with a regretful expression that Hayate is the only one she can open up to like that. Hayate mentions she has calculated that Kokoa cooled down in 45 seconds, "faster than before," and Kokoa tells the former she should tell her some reassuring words instead. Hayate repeats both of the things Kokoa told her and causes Kokoa to become flustered. Hayate gleefully tells Kokoa that she is happy Kokoa is able to show her true self to her, and how it makes her feel special.

Fanon
Hayakoko is currently both girls' most popular ship. The ship became quite popular the moment their characters were revealed and the two were announced to be canonically dating in their respective character descriptions. As they are still new characters, they also barely have any rival ships.

Despite having openly sapphic characters, D4DJ is known for leaving ships semi-canon, the most renowned case being Tsubaoi and other major/"main" ships that could be interpreted as semi-canon, such as Kyoshino, Miyuharu and Nagihiiro. As such, it became a huge surprise to fans that D4DJ has actually canonized their relationship.
