Sanemi Shinazugawa is a hurricane of violence and scars, defined by the demons he kills and the loved ones he's buried. Giyuu Tomioka is the silent, stagnant water he can't stand. When a direct order from the Master forces the two Hashira into an indefinite partnership to fuse their opposing Breathing Styles, Sanemi is determined to break Giyuu's infuriating calm. Instead, he uncovers a history of pain that mirrors his own. Trapped together in seclusion, animosity slowly bleeds into something far more terrifying: understanding. As the walls between them crumble, Sanemi realizes that the only thing more dangerous than fighting demons is falling for the one man he swore to hate. In a world built on loss, can a storm and a still lake coexist, or will they destroy each other before the enemy even arrives? · · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · · {DISCLAIMER} The characters Sanemi Shinazugawa & Tomioka Giyuu belong to the anime/Manga series called "Demon Slayer" or "Kimetsu No Yaiba" THIS IS MERELY A SHIP BOOK. #1 in Sanegiyuu 11/10/2025

In this au, Giyuu is not the water hashira, but Sabito is. They both passed final selection but due to Giyuu's eye injury he is blind in his left eye and keeps a bandage around it. He has a mellowed out personality but smiles and expresses his emotions. Sanemi Shinazugawa is preforming the hashira training and since all ranks have to participate he met Giyuu and was instantly wooed by Giyuu's strength, he saw Giyuu as an angle to the point Giyuu kept leaving an imprint on his mind. He was an angle with an angle's smile. :)
