Set Introduction
''“Attention citizens of Kaina City! We are commandeering this here port! Now, don’t you worry about a thing, once we’re done here, you won’t ever need to use a boat again! …And no one tell that captain we’re here.”''

''“What in the world?” Ema muttered under her breath. “Skip town for a year and the whole place turns upside down. Excuse us a moment, miss Oblay. Sanaito and I need to take care of this…”''

Storyline
Chikyu: Chaos Rains takes place in the spring following Monsters of Chikyu, with Ema, Sanaito, and Karina returning to Ema and Sanaito's home of Hoenn to establish diplomatic ties between it and Tohjo. When they arrive, they discover the region has fallen into turmoil in Ema's absence, with many of Hoenn's sailors having created "the Aqua Crew," who's leaders plan to awaken an ancient slumbering monster in order to raise the sea level in order to make the region more dependent on them. A counter-group headed by "the Magma Council" has been keeping the Aqua Crew at bay, but rumors swirl that they plan much the same, to awaken another deity that will dry up the sea completely.
