The theme of Turning the Ark is self-annihilation. In this world, characters are divided into two factions.

The other is the clan of "Huan," whose members all possess features resembling those of wild animals (such as animal ears or tails), akin to creatures that would appear in Western fantasy mythology. Players take on the role of the leader of the "Huan" clan. While exploring the truth behind the self-annihilation, they must also uncover what secrets are hidden within the "Ren" and "Huan" clans...
