Snake Whisper (GxG)

In the shadow of weeping willows and marsh-lights, a Breathing style was born that knew no fury. Reptile Breathing is the art of waiting, adaptation, and the cold-blooded strike. Its practitioner, Midori Habu, became a Hashira while being more of a ghost than a warrior.
Her world, built on logic and survival, was shaken by a single smile. Kanae Kocho, the Flower Hashira, became the warmth Midori had never known and so desperately needed.
But when Upper Moon Two extinguishes that light, Midori's world does not explode-it freezes. This is a tale of quiet love and even quieter grief; of how the Reptile Hashira retreated into the shadows to help her beloved's sister prepare poisons. She will not interfere in the fate of the main protagonists, but her invisible presence and a final Eleventh Form, forged from pure devotion, will alter the course of the final battle.

English isn't my first language, so I apologize for any spelling mistakes or bad/wrong wording in my fics.
