Sun, sand, and girls in bikinis playing volleyball... it's Eita's dream come true! Except for one little detail -- these girls are half-animal. Eita's beach fantasy quickly dissolves into a nightmare when a giant squid shows up, bringing naughty tentacles to the party. All too soon, Eita, Aero, Jawea, and Asterio must leave their beach paradise to seek out Steela, the Witch of the Deep. But, first, Eita must face his murkiest opponent yet: the evil Angler!
