Elly is the gatekeeper of Yuka's mansion, which is a border between the dream world and the real world. It's so rare that people come there that she is rather surprised when both Reimu and Marisa show up one after another, and fails miserably to stop both of them from entering. She blames it on the long time it has been since she last fought.
