Summary
On the eve of his sister’s wedding, Giyuu finally believes life might be improving. After losing their parents young, Tsutako has been his entire world, and seeing her prepare for a happy future fills him with hope.
However, that hope is shattered when a demon attacks their home in the night, leaving Tsutako dead by morning. The villagers insist it was a bear and claim grief has twisted Giyuu’s memory, but he knows what he saw. Branded unstable, he is sent away to live with a distant uncle who promises to “heal” his troubled mind.
Alone and far from home, Giyuu struggles to survive both his grief and the suspicion of those around him. When all hope seems lost, fate finally favours him and leads him to Sabito and Urokodaki-sensei. Now, Giyuu must decide whether he can overcome his past and become strong enough to defeat Muzan Kibutsuji—or fail to protect those he swore to save.
OR: My own AU of Demon Slayer with Giyuu as the protagonist.

Summary
When his vision came into focus, a figure stood at the center of the field, a boy Sabito’s age. Sunlight illuminated the contours of his silhouette, yet the shadows cast left his features in a void of darkness.
The boy was sticking out his thumb, despite being covered by the shade and blinding rays, Sabito could vaguely make out the glow of a matching red string wrapped around it. Radiating like scarlet hues of the golden hour, glimmering above dips and craters of the vast endless ocean.
The sight was serene, ethereal, almost transcendent.
Sabito opened his mouth to call out to the boy, yet the name stayed stuck on his tongue. Every time he lifted his feet, the steps he took became shorter, shakier and ever more desperate, the grip at his ankles pulling harder than ever before.
As Sabito stepped forward, before he knew it, he was pulled beneath the earth, into an aggressive thrashing current.
——————— ༄.° ———————
Or,
Sabito awakened from a coma two years after his untimely ‘death’ during final selection. Blessed with the chance to live once more, would he fight for a better future for the people he loved most? Or would he let himself drown beneath the torrents of his past?
