They should have called this Magic Knights Wolkenritter instead...
But I like the Chrono idea, but only if its a comedy, and there should be a prerequisite scene of Amy denying him his juice every week. You can substitute that with scenes of Amy rubbing melons or Chrono combing Amy's messy hair, or the catgirls chowing down on Chrono. There's no justice in this world, otherwise.
Chrono Crissis!
