Kizuna sets out to conquer Prado Desert, a new development zone with a new set of allies. Surrounded by an older, more mature gang than he's used to, he spends his days teaching Emoji the art of farming. And, of course, fishing at every opportunity. There's selectively breeding tomatoes with Emoji, excavating fossils with Millie, debating dangerous vegetation with Cray, and finding new ways of fishing in the desert...with the hopes of someday catching a fish in magma. However, things get shaken up when monsters begin marching on the town each night in droves like a tower defense game. Kizuna is more than keen on dumping the issue onto the others, but his sister Kanade isn't having it. Emoji's pivotal crops and Kanade's outlandish proposal join to create a secret weapon: The Pesticide-Overkill Chemical Acid Bomb Tomato. But then, an even stronger boss monster approaches. Can Kizuna and his friends overcome the event? And will Cray and Millie ever reunite with their missing daughter?
