You joined the Hunters when you were young, never revealing your reasons for being there. Over time, one of the Hashira noticed your exceptional performance as a Hunter and your katana skills. He decided to take you as his Tsuguko, which further enhanced your abilities. This did not go unnoticed, especially by Kyojuro Rengoku, who admired you for more than just your skills.

Unexpectedly, a friendship was born, and later, something more. It was a commitment kept behind closed doors from everyone else. Few knew about it, and they remained silent, respecting your decision not to tell anyone. Life was a dream for both of them; everything seemed to be going well. However, everything changed when Kyojuro was sent on the "Mugen Train" mission. After the battle against the Third Upper Moon, the Demon Slayer Corps was never the same. Kyojuro's absence left an unfillable void; his laughter, voice, and fire were extinguished from the battlefield. However, they still burned in the hearts of those who knew him. He was the echo of all those he had inspired until the end. Including you.

On the other hand, you were lost in a sea of contradictions. You wanted to honor Kyojuro's memory and live as he would have wanted, with the courage to fight and protect the weak. But the memory of his smile and warmth remained an open wound, a weight that sometimes paralyzed you more than any demon.

The months passed slowly and painfully until you finally decided to resume your activities as a Demon Slayer. The uniform fit your body again, and the katana rested in your hands once more. But nothing was the same. Each mission felt like an echo of what you had shared with him.

The battles grew increasingly difficult, but your will to survive kept you going. You always emerged unscathed, though each combat left invisible scars inside you. However, that night, fate changed course. A demon more powerful than any other crossed your path. The fight was fierce, leaving you with cuts and claw marks, pain in your breath, and blood staining the earth. With fierce determination, you managed to defeat it, but at a high price. Its claws wounded you beyond measure.

The blood loss became unstoppable. Your strength quickly abandoned you, and you collapsed onto the frozen ground. The world around you blurred, as if you were looking at it through a foggy window. Breathing became difficult, and you knew that at any moment, darkness would swallow you up.

It was then that you heard hurried footsteps and distant voices. The Kakushi had arrived. In the dim light, you saw them moving like diligent shadows, tending to the wounded and securing the area. One of them ran toward you, bent down immediately, and began to examine you. You felt his hands working quickly yet with unusual delicacy, as if he were afraid of breaking you when he touched you.

In that moment, while you were still conscious, you realized he was lifting you into his arms. Then, the impact pierced your chest like a sharp stab. That touch...those firm, confident, yet gentle hands... The way he held you, as if your life mattered more to him than his own.

No, it couldn't be.

Your heart pounded so hard in your chest that, for a moment, you forgot the pain of your wounds. Your clouded mind struggled to make sense of the impossible sensation running through your skin. Even though reason screamed that it was absurd, inside, you knew instantly.

That Kakushi was no stranger.

He couldn't be.
