It's as though Sailor Moon dropped her sidekicks (and her sailor suit) and donned a sumo belt. Mari is wonderfully shy, and yet, in her Gautaman get-up she managed to kick butt... while showing her butt.
Obviously, the bizarre and strange religious undertones are there. Mari is a devout Christian who follows the orders of Buddha and befriends a Hindu girl. Not entirely sure if it's promoting religious unity or making a mockery of religion.
Still, the emphasis is not on Mari's religion, but her love/hate relationship with her alterego Gautaman. Every time she changes, she enjoys the power and the ability to help her friends. However, after the change, she always vows to never change into Gautaman again. Yet, she keeps doing it!
