Technically, anyone can use it. There isn't some hardwiring in Japanese minds that prevents girls from physically saying boku. :P

Socially and culturly, it tends to be more masculine and is used by males. Michaela was originally a genderless forest spirit, so that is probably the reason (assuming she used boku for the entirety of Wiegenlied).
