If I overlay Hiruma with Hida Atarasi, can I use Hiruma's movement actions at all? I was wondering because they actually make reference to Hiruma.
Relavent text:
Hiruma
Battle: Target a Personality in your home not targeted by Hiruma this turn. Move him into Hiruma's battlefield. Battle: Target a Personality you control in the current battle not targeted by Hiruma this turn. Move him home.

Yes, you can (variation of "Self-referential cards" rules, Diamond rules, pg. 69).
