Shiri

Shiri (シュリ, Shuri) (sometimes romanized as Shirley) is a member of the Dollars. She is a young Russian woman (Italian in the English dub) who walks around with a writing pad around her neck. If somebody is looking for something, they write what they are looking for on a page of the writing pad in the hopes that whoever found what they are looking for will read it.
