Maru
Maru is one of the two girls that led Watanuki into Yūko's shop. It isn't stated whether the girls were created by Yūko, Clow Reed, the both of them, or someone else entirely, but since they have no souls and cannot leave the shop, it can be assumed that they were created there. Spoiler Possible Powers-In chapter 126, Yūko explained why Maru and Moro are required to stay inside the shop. The shop itself is not seen by anyone unless they are fated to do business with Yūko. Maru and Moro's concentration is what is keeping the shop in existence. As a side-effect, they have long deep bouts of sleep. They help out around the shop, but mostly act as the cheering squad. They almost always speak in unison, or close to it. Watanuki seems to get along with them most of the time, at least when they are not dragging him into one of Yūko's plans. It is noted that Maru and Moro's full names are both words which mean "exposing oneself in public" – similar to "flashing" and "streaking" in English, aPokaż więcej
