Maru and Moro are like twins and mostly speak at the same time. They are also “spirits” that are strongly tied to the shop, so much so that they can’t leave.

Maru is the more mature one, though she can be temperamental at times. Moro is the seemingly younger twin and in that sense can be more innocent. Both are quite childish.

They are quite loyal to Yuko and become really fond of Watanuki.

They show up quite frequently, but have very small lines.
