How can I save a Pokemon I want to keep so I can restart the game (without using the Pokebank)?

I found out that male customization sucks in X/Y, so I'd like to start over as a female character.

However, I got Absol from Wondertrade and I'd like to keep it on the new save. I know that you can use Pokemon bank, but my family doesn't allow me to "buy" it.
So my question is how can I do so without Pokemon Bank?

@Timelord64 asked a good question. Without PokéBank, you can only resort to trading. If you can find someone who is willing to give you your Pokémon back when you need it, you will be able to "save" your Pokémon thus getting it back after you restart your current progress.

Otherwise, note that Absol can be found and caught on Route 8 on both X and Y games and in Friend Safari if you have a friend with that Pokémon in friend safari.
