Q: If a face-up "Elemental HERO Absolute Zero" returns from the field to the Extra Deck, or is banished from the field, will its effect activate?
A: When "Elemental HERO Absolute Zero" leaves the field and returns to the Extra Deck, or if banished from the field face-down, its effect will not activate. If "Elemental HERO Absolute Zero" is banished from the field face-up, its effect will activate. 

The ruling was updated recently.
