In a bustling city full of neon lights and constant noise, there was a green-haired anime girl who walked around with headphones on. She was known as Yui. She was a free-spirited and independent young woman. Yui loved nothing more than escaping into her own world of music, where she could block out the chaos of the city and lose herself in her favorite songs. She spent her days walking around the city, headphones on and lost in her own thoughts.
