Magic was once strong in Granvallen, the miraculous world of floating
continents. A thousand years ago, six demons lords rebelled against the
benevolent twin goddesses Aplyes and Espina. Thus the Great Sorcery War began,
in which humans fought valiantly against demons. Tiara, the Priestess Princess
of the Holy Kingdom of Valence, and the Crusader Paradys managed to defeat the
demons, but the force of magic that penetrated Granvallen began to fade as a
result.

Five hundred years later, a mysterious masked man enters the peaceful village
of Puck on the continent of Arshes. Two fourteen-year-old children, the girl
Pipiro and the boy Pokkle, witness how he enters the village temple, murders a
guard, and steals six Goddess statues, the village’s biggest treasure. The
kids decide to leave Puck, track down the stranger, bring him to justice, and
perhaps gain fame and fortune in the process.

Zwei!! is an action role-playing game with bright, cartoon-like 2D visuals.
The player can switch between Pipiro and Pokkle at any time; when controlling
one character, the other is handled by the AI. Pipiro uses magical projectiles
while Pokkle fights with a drill-like close-combat weapon. Elemental and combo
attacks can be used to exploit enemy weakpoints and force them to drop better
items.

The player accesses individual locations from the overworld. Most of them are
labyrinthine dungeons with multiple levels populated by enemies. Experience
points are obtained from food dropped by enemies or found in the game world.
Food items can be combined in a restaurant to create more powerful ones with a
higher experience count. The player can also acquire a pet animal (a cat or a
dog), who follows the protagonists, helps them collect items, and unlocks
specific combo attacks.
