As a result, the inhabitants of the Kingdom of Alysia were trapped inside their child bodies forever - humanity was frozen, doomed. Blamed and discredited, the five legendary warriors were forced into hiding. Now, Darkhell has returned with a terrible plan: to capture the Gamera Tree and exploit its magic to enslave the world.
