Space and Time
Space and time is an instrumental background music to the anime xxxHolic.
The song has an eerie and mysterious feeling to it but also feeling somewhat magical. It is considered as Yuko Ichihara's theme song mainly because it plays every time Yuko explains something serious or when she says a monologue by herself. It can also be said that it is Yuko's theme because the title is "Space and Time" and Yuko is thumb|300px|rightthe time and space witch.
