(Meariri) (Kirasaya) Crimson Nocturne

Short summary: A vampire story with our favourite Kakegurui characters

Long summary: Mary is a vampire hunter that has been hunting down vampires posing as humans for years.

One day the organisation she works for introduces a new vampire hunter, one with brilliant blue eyes and strange grey hair. The new recruit has extraordinary kinetic vision and speed. The two start to bond and grow closer when Mary starts to notice that this vampire hunter is not who she thought she was.

Mary returns to the organisation after a one week break only to find the headquarters burnt to the ground and her new friend to be missing.

She goes on a manhunt for her friend and comes across something startling: That very same friend may very well be the same person who destroyed the organisation.

Mary proceeds to embark on a journey of betrayal, love and self-discovery, with her eyes open to a new world of which she has never seen.
