A part of her is hoping that she’s waited too long, that the stains will never be washed away. Besides her ashes and charred bones, this blood is all that’s left of the body that belonged to her sister.

An ordinary moment, before the dawn, before the rain.
Just a little something I wrote to indulge my bittersweet thoughts about post-canon Giyuu being a dad.

Summary
When Giyuu was four, his mother took him and his sister to see the ocean for the first time.
It’s only six months before her death, six months before he and Tsutako became orphans, and if Giyuu is honest, his memories of that day have long since faded. He knows they took a train, knows Tsutako was the first to rush into the water still warm from summer’s fading light. He knows he was more reluctant, that he held his mother’s hand while he watched the waves crash upon the shore.
“Are you afraid?” she asked, her frail fingers carefully intertwined with his own. Giyuu shook his head. “No? I didn’t think so. Do you not want to swim then?” He shook his head.
“I want to stay with you,” he said as if it was the most obvious thing in the world.
Together they walked across the beach, the ocean eagerly nipping at their feet. Eventually Giyuu will swim, eventually the water will take him as her own. But not today.
Today he was his mother’s son.
Blood in the house. Blood on the mountain. Blood in the water.
Alternatively: a nonlinear study of Tomioka Giyuu.
