When I saw how different the beginning of the manga was as opposed to the anime I was shook because I saw how when Rukia's soul reaper's powers were given to Ichigo in the manga she became so small (small enough to fit in a Coffee Mug) whereas in the anime nothing like that happened. But, I always loved seeing the captains, I'm partial to Byakuya, Kenpachi, Toshiro but old man Yama and Myuri get me frustrated often. I love how the soul reapers get a partner in their swords.
