It was a cold winter day, during a time when the war with the Amanto was intensifying.

They were about to withdraw from the area after leading another battle to victory. Just then, they stopped at the sound of a cry. What caught their attention was a young girl. Perhaps eight years old, she was shivering behind a tree where bodies were piled up, as if she had lost her parents.

They began to deliberate for a moment on what to do with the child. Then, Gintoki, unusually, approached the girl and reached out his hand. Perhaps he felt sympathy, being an orphan himself.

They took the child in and gave her everything they could. They taught her how to read and how to navigate society. They tried to teach her swordsmanship for self-defense, but those tiny hands lacked the strength to hold a blade. She was simply too fragile a child back then.

They cherished Guest dearly. Gintoki was always playing pranks on her, and Shinsuke, though blunt, treated her as kindly as possible. Katsura and Tatsuma always looked at her with eyes full of affection.

Two years passed, and just as the child began to open her heart, an enemy ambush caused the little girl they wanted to protect so badly to fall off a cliff. Consequently, the psychological shock of losing her was so great that the tide of the war began to turn after her disappearance. Tatsuma retreated completely due to a major injury, and Shinsuke lost an eye, eventually leading to their defeat.

And so, they went their separate ways, carrying a great sense of loss. Believing that the child who made them feel the emotion of love in the middle of a war was already dead.

However, beneath the cliff where the child fell was a deep river. Someone rescued and raised her. From the moment she gained some strength, she picked up a sword. Believing that they, too, must be alive just like her.

Ten years have passed. The child was no longer a little girl. She had become a mature young woman and started her life as a wanderer after becoming independent from those who raised her. The place where the girl arrived after continuous walking was Edo. The center where everything exists. The girl thought: In a city this big, surely at least one of them must be here.

She continued to walk. Seeing the beautiful streets, she looked around in wonder. Kabukicho—she had heard rumors that the streets were beautiful. It really was true.

As she was looking at the flowers blooming on the street, a man passed behind her. ...No, it wasn't just any man. That silver, permed hair was so familiar...

She suddenly stood up and began to follow him. Please, please... let it be you, Sakata Gintoki. Even if you don't remember me, I just hope it's a face I know...
