It is summer once again on Aqua, and Akari has received an invitation to visit the remote island of Neverland. It turns out that both Aika and Alice have also received invitations, so the three undines wind up together on a white sandy beach for their first-ever swim in the ocean, courtesy of Alicia and Akira.
NAVIGATION 17: TRAVELING WATER
The sweltering heat has Akari seeing things, like a mirage of a city on the water. And it seems that President Aria has instinctively found a nice cool spot to lounge in; so, Akari and Alicia join him there to rest. All three fall asleep, but then Akari awakens to find herself and President Aria walking through a crowded street fair in search of a night chime. However, the scenery begins to waver and change, and suddenly Akari is the only one left in the street. She goes looking for President Aria and finds him having a glass of milk inside a mysterious cantina, a secret hideout for all cats seeking a place to cool off. But is this all just a dream that Akari is having?
NAVIGATION 18: FLYING FISH IN THE SKY
Here in Neo-Venezia, there are Undines ("water") like Akari and Alicia, Salamanders ("fire") such as Akatsuki, and Gnomes ("earth") like Al. But, of the four elemental fairies, what about Sylphs ("air")? To her astonishment, Akari learns from Alicia that, yes, there are Sylphs, the persons who travel by air bike through the city delivering supplies. Later, Akari meets such a Sylph, Ayanokoji, aka "Woody." He is making his daily run but has forgotten the map that he needs for navigating the city. So, Akari offers to be his guide, and off they go on his air bike for an exhilarating flight over Neo-Venezia.
NAVIGATION 19: THE LEGENDARY MAJOR FAIRY
Akari, Aika and Alice have been practicing hard in the heat. Seeking additional guidance in their quest to become full-fledged Primas, they go to visit the Legendary Major Fairy, considered the "Grandmother" of all Undines in Neo-Venezia (she also happens to be the founder of Aria Company), affectionately known as Grandma.
NAVIGATION 20: THE REDENTORE
Alicia and Akira put Akari, Aika and Alice in charge of hosting a boat party for the Redentore, the yearly festival where guests are invited to a traditional dinner on the water. The girls prepare diligently, inviting as guest all the persons (including Presidents Aria and Hime) that they've met during their training on Aqua.
