I bound blue dye

My name is Mikami Yuu, and I am a first-year student at the Soul Society, Shino Academy of Spiritual Art.
I have a friend who will be a little famous in the soul world in the future, and his name is Aizen Soyousuke.
Unlike this friend with great ambitions and lofty ideals, my goal is very simple. Through hard work and diligence, I will become the chairman of the [-]th Guarding Team after graduation, and then become a warrior class, living a life of lying down and sucking blood.
Until one day, a thing called "Cultivation Binding System" suddenly appeared.
Whenever Aizen improves his strength, my strength will be automatically synchronized to the same level as Aizen.
Then, what to do in the future is very clear.
"Souyousuke, you have to work hard, as long as you work hard enough, I can live the life I want!"
