Secret- Maid Outfit

Machinegun Angel character Secret, who is a clone, like Gauge, in her maid outfit. Gauge meets Secret while staying at the hotel she housekeeps at. There is an instant connection between the two, not to mention Gauge believes Secret is a clone of his first love Ellie, Which turns out to be true by the discovery of a birthmark.

Secret shares a past much like Gauge's and it could be possible the two may share more than that in the story ^^
*wink wink*

In case you havent figures it out, all the clones in MGA have grey hair and red eyes.
