Kasuren

Kasuren is the het ship between Kasumi Toyama and Ren Nanahoshi from the BanG Dream! and From Argonavis fandoms.

Canon
Kasumi and Ren are the main protagonists of their series as well as the vocalists of their bands, Poppin'Party and Argonavis. While Kasumi is a second-year high school student as Hanasakigawa Girls High School, Ren attends the Law Facility of Kamogawa Music College. What links them together is the fact that both were inspired by an event in their childhood to chase after their aspirations; upon stargazing one time, Kasumi suddenly heard the "Star Beat" and started looking for it, while Ren was enamored by an outdoor concert and he started singing in hopes of reaching the big stage in the future. Whereas Ren started singing after witnessing the outdoor concert, Kasumi didn't start playing the guitar until she was in high school upon coming across the Random Star at Ryuuseidou.

Kasumi and Ren have opposite personalities. Kasumi is very bubbly, easily befriends people and will jump into anything that seems exciting. She also has her sentimental side, and can be quite sensitive. Meanwhile Ren, who can be quite passionate and straightforward when it comes to the things he loves, is a shyer person. He became a bit of a loner after a bad experience in his middle school's choir, at least when it came to singing. However the few things they share personality-wise is their passion for music, as well as them disliking people who belittle or laugh at others' dreams no matter how trivial or small they might be.

Kasumi and Ren are also attributed with the stars, as Kasumi has her aforementioned "Star Beat," describes the things she finds exciting as "sparkling and heart-pounding" (kirakira dokidoki), and also wears her hair in star buns, meanwhile Ren's surname Nanahoshi means "Big Dipper", which is a constellation of seven stars. They both enjoy karaoke as well, as it is one of Kasumi's listed hobbies, and Ren used to sing all alone in karaoke booths before he was found and recruited by Yuuto Goryo to join his band (Argonavis) as their vocalist. They also love fast food, as Kasumi mentions that she loves french fries so much she could eat them endlessly, and Ren loves Lucky Pierrot's Chinese chicken burgers to the point where Banri, Argonavis' drummer, asked whether Ren loves singing or their burgers more.

Fanon
Kasuren is a huge rarepair, heavily overshadowed by Kasumi and Ren's most popular ships KasuAri and Nayuren. It is fairly unpopular due to their age gap, the fact that the two have never interacted and its somewhat infamous nature of being one of the "Straightdori" ships. What also adds into its unpopularity is that From Argonavis is not a very well-known franchise, was overlooked and scorned over by the BanG Dream! fandom after its announcement, and the fact that a lot of people prefer to headcanon Kasumi as a lesbian.

It is sometimes shipped alongside with other Straightdori ships such as Nayukina.
