Although they have been sent to deliver a message to Gala, the leader of the planet, Noa hopes Gala can provide answers to questions about Noa's origins. Meanwhile, in the Yellow City, Ludovique is again attacked by Agape's faithful followers. The success of the Aqua mission is essential to reinforce Ludovique’s position as religious leader. But when Noa is around, events always take an unexpected turn.
