Yuko is a witch with the ability to grant wishes. She is a fun and whimsical character who enjoys drinking alcohol and teasing Watanuki. 

In spite of her seemingly easy going personality, she is in fact quite a mysterious character. She has an amused and otherworldly tone when speaking of possibilities and occurrences, as if she knows what is to come.

Despite her constant teasing of her part-timer, Watanuki, at times she shows a motherly side to him. 

If cast, I will ask to get in the call as this is a very important role in the series. I believe that to do this role well, we would need to discuss more about the character as this character knows way more than you would expect about the story. This is only for this specific role.
