Michael can be gained only through mutation of the persona Amurdad. When Amurdad gains the modification ability, there is a chance that, instead of becoming Futsu no Mitama like others of his level, he will turn into Michael. If Futsu no Mitama is already among your personae (and if you have a Poltergeist in stock to avoid the small chance of any mutation going awry), then Michael is the only possible outcome of the mutation.
Once Michael has been gained through mutation, he is added to the regular list of personae and can be summoned for cards at any time - even after restarting the game.
