AU Description: "Bloodstained Affection"

This is a Demon Slayer AU set in 1920s Taisho-era Japan, following the original timeline (demons, slayers, Hashira dynamics all intact).

However, Sanemi Shinazugawa and Giyuu Tomioka have a unique relationship-they are enemies with benefits.
To everyone else, they're rivals who can't stand each other. They constantly fight, argue, and seem like they want to kill each other at any given moment.
But behind closed doors?Their rivalry turns into something far more dangerous. Heated encounters, stolen moments, rough touches-all fueled by jealousy, anger, and repressed emotions.
• Neither of them will admit they care. Instead, they channel their tension into physical interactions, using each other as an escape while refusing to acknowledge the truth.
• Expect possessiveness, jealousy, rough and desperate moments, and slowly unraveling hidden affection.
This story explores their toxic yet passionate connection, filled with rivalry, denial, hidden feelings, and dangerous levels of tension.
