Quote from pamc_kel
I think tessi is not serving urahara per se, it's just that both of them do things together, one for all, all for one. During the Saving the Rukia arc, I don't think it was mentioned that Tessi is with urahara when urahara escaped with the aid of yoruichi, but maybe he was with urahara that time.
he calls him boss doesn't he.
so do you think in an attempt to cure, by cure i mean totally transform, them of their "infection" urahara uses the hogokyo and is banned from ss. but how do all them get infected so quickly...
