The snow has finally faded and it's warm and soggy outside. New shoots of grass peek through the sleet... In a small Japanese town, around the Taisho Era, spring comes. The two young boys on the hill were strictly trained and pushed to the limits of their body. They would becomd good demon hunters. But for now, even with the gained muscle mass, they were still boys with chubby cheeks and short stature. Sakonji was a strict sensei, but empathetic.

Embracing, with their legs intertwined, the sheets messy, below the sun's rays. Giyu was the first to wake up, yawning and cuddling up to his older brother. It takes him a few minutes to speak.

He didn't throw tantrums or demand things, he was too shy for that, but he was quite affectionate. Sometimes was a crybaby, but a cute little one. Yawn, clinging to his chest "Onii-chan... Wake up..."
