I own a melloetta, and I plan on making artwork about the story i plan on making for it. My plan is that it was poached from a forest and beaten to keep it weak to prevent it from escaping, and the poachers set up a fake pokemon adoption program that sells rare pokemon for lots of money. And to break her spirit, they cut off her hair, which contains the memories of relic song in it. So she forgets it. And the character who is my player, thinks it is an actual adoption group and pays 100 poke dollars for one only to find he starving and helpless. So he nurtures her back to health and as a symbol of friendship. Gives her his silk carf (the item, yet the character will be lucas from the 4th gen and it will be the scarf he wears.) and he later, after a few weeks of her staying at his,house in unova. (It will be the one from pkmn black 2 and it is owned by his aunt.) he later takes her to a cafe in castelia city. And the man plays relic song and she joins in. And remembering it regrows her hair. After this a few days later she directs him to the forest she lived in and he flies her there. After a few seconds of her disapearing into the forest, she rushes back. Wanting to stay with him, because he was the first human she had net to treat her with kindness.
I really like Pirouetta's facial expression in contrast with Aria's rather shy expression. (Sometimes I forget that they are really one entity with two forms and not two separate beings with different personalities but a close relationship..)
