Yeah. Yuuko has so many and complex functions in CLAMPverse sometimes I feel they understimate her a bit as a character. She might not be the main character in neither of the series she's in, but she's like an axis who keeps the plots together. She's not even just a drunkard woman who just lives to tease and torment the uke the easily annoyed boy who works for her. I don't know. You can like her or dislike her or be indifferent to her, but do it taking this into consideration.
