Ova Micah sends the Hestia familia (plus Ryuu) on a quest to recover some medicinal herbs on "Paradise Island", which would also double as a vacation for them. Hestia and Lili (also Haruhime) fight over who should spend time beside Bell and choose to decide it with a swimsuit competition. The girls each show off their swimsuits, flustering Bell, and when he's asked to pick the winner, they are suddenly surprised by the appearance of Ais, sprouting a mushroom from her head. Acting uncharacteristically cheery, the others figure she has amnesia, and to help her they'll need to find the fabled "Everything Flower" hidden at the centre of the island, which can grant the holder's deepest desires...
