You'll have to wait for the next clue Clue 1: is a fairy type Clue 2: it's genderless Clue 3: it's a legendary/mythical
Also... Just saying this for constructive reasons. But the third clue isn't helpful, considering all legendary/mythical fairy types are already genderless to begin with. Ignore this. I got the order of the clues mixed up and forgot there are also non-legendary, genderless fairy types.
