Lavinia

Queen of Sweet Wonderland. She says that any resident of Sweet Wonderland that finishes her collection game will have their wish granted (in the case of Alice, he simply wants to return to his own world).
Lavinia is a girl of small build who despises being called "little" and will not hesitate to decapitate anyone who calls her such. Unlike the Queen of Hearts in Carroll's work, Lavinia is a fair and responsible ruler (but equally temperamental).
Despite knowing about everything happening in her kingdom, Lavinia is very innocent in regards to adult matters, so she is very eager to use Alice as a "guinea pig".
Rouge13 and Emudori are her direct subordinates.
