I think I may have a more silly Ukitake muse then anyone else I know of. This is all well and good I suppose because it's a good match for shuufish's Shunsui muse.
But still.. when Ukitake moved in to the muse-box.. him befriending Jin and vice-versa was the very LEAST that I thought would happen. But I will admit it is very cute.. very very cute. They make a good duo when Ukitake and Jin are stuck in the muse box and with no where to go. And really, with the rabble-rouser that Jin is.. it seriously is nice that he has someone who will put up with him.
And Ukitake's tolerance level = HIGH
