lol! I really enjoyed all of them! Especially the Seto and Mokuba one ( lD Seto is a good older brother, despite being a cruel person to everyone else), and the Byakuya/Yuzu one (Poor Ichigo, but Byakuya will take care of his youngest sister!).

And the Kaien/Rukia one was so sad. I always thought that Rukia might have unrequited feelings for him, but since he was married and in love and died avenging his wife, she was happy with their relationship as superior/subordinate and nakama/friends. D;
