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

~OBAGIYUU: MARRIED AT FIRST SIGHT AU~ Obanai Iguro didn't sign up for this. Well, technically he did - but only because his best friend (Sanemi) wouldn't shut up about it. Now he's about to marry a stranger on live television. Giyuu Tomioka didn't sign up for this either. His best friend (Mitsuri) signed him up while he was feeding cats. Two introverts. One reality show. Zero idea what they're doing. What could possibly go wrong? (Spoiler: everything. And maybe...something beautiful.) !!! Updates will probably be twice a week! !! I do not own the show "Married at First Sight". Credits to the creators; it's amazing! !! I do not own cover image; Credits to the artist💖
