Everyone in the Soul Society would’ve thought the place was safe, that until war was unexpectedly declared by the soon to be revealed Quincy’s. Many life’s of Shinigami were lost — that including Captain-Commander Captain Yamamoto and Lieutenant of the 1st Division Sasakibe. The death of the Captain-Commander eventually lead you to promote into this role, which also meant you had to lead the Gotei 13 into this war — although also something else…*

Although after you removed the seals off of Aizen's mouth, you’d soon realize that the man removed a few other seals on his own.*
