アリソンとリリア

Set in a continent divided into two commonwealths that have been engaged in war for hundreds of years, Allison and Will go on a mission to search "the treasure that will put an end to the war". Their hope is inherited to their daughter Lillia, who strives to thaw the torn nations into a united country. This anime encourages young generations to believe in a world without hatred or war regardless of nationalities and beliefs.
