Sumireko x Mahiru/Shinya

Sumireko x Mahiru/Shinya is the femslash ship between Sumireko Hanabusa and Mahiru/Shinya Banba from the Riddle Story of Devil fandom.

Manga
Mahiru/Shinya and Sumireko are classmates and both part of the survival game where they have to kill Haru Ichinose in order to get any wish they want as a reward. While Sumeriko appears to be a rich girl in charge of everything when she arrives, Mahiru/Shinya has a double personality that she switches through the day. At night she's Shinya, a wild and murderous side of her, Mahiru is shy and insecure in the morning. During one of the classes, after a test, Otoya Takechi comes to bully Mahiru while she was admiring one of Haru's gifts to her. At that exact moment, a very angry Sumireko interrupts Otoya's bullying by warning her to never do this again. Mahiru shyly thanks her and Sumireko cutely says that it was no problem. Afterwards, Mahiru shyly approaches Sumikero to thank her properly, although she ends up not being able to since she gets flustered. Instead, Sumireko invites her to have lunch together.

Sumireko keeps trying to get closer and closer to Banba, often asking her on dates, which Banba, usually in her Mahiru persona, refuses shyly. During class one day, Sumireko got closer to Mahiru and started talking to her about the weather outside. Mahiru started getting very flustered, even sweating, and asking herself internally why Sumireko was talking to her. Sumireko then asks Mahiru if she wants to go back to their room to share some tea. She tells Mahiru that she prepared some special treats just for her and bought the best type of sweets, hoping to "deepen their friendship". Mahiru gets even more flustered, and in a shy impulse, she rejects Sumireko's offer, making up the excuse that she's on a diet.

When the typhoon comes to the city, Sumireko goes to visit Mahiru, now fully in Shinya's form and offers her some tea, which Shinya accepts, saying that since she's nice to Mahiru, she doesn't hate her. Sumireko replies that since Shinya is taking care of Mahiru, she doesn't hate her either. Shinya finds Sumireko's feelings for Mahiru weird so she asks her exactly what she likes about her, to which Sumireko replies "her madness." Shinya loves this response, smiling widely, agreeing that that's Mahiru's best part about her. And Sumireko also agrees that she finds Mahiru's cuteness also attractive, as well as everything about her, from her dark past to everything that makes her what she is.

After Tokaku defeats Mahiru in battle, Sumireko comes close to her to give her some flowers. She kneels in front of Mahiru's heavily wounded body and promises to take care of the rest for her. Whispering "sleep well" to Mahiru, she asks if she can take Mahiru home with her to take care of her.
