Ryza is een gewoon meisje. Ze is het saaie dorpsleven beu en ontvlucht het dorp om met haar goede vrienden op een geheime locatie samen te komen om over hun dromen te praten en spannende avonturen te plannen. Op een dag besluiten de vastberaden Ryza en zijn gezelschap naar het verboden 'eiland aan de overkant' te gaan als hun eerste verkenningstocht. Samen met de alchemist en andere vrienden die ze daar ontmoeten, beleven ze een 'zomeravontuur' dat ze nooit zullen vergeten.
