Chaos Legion

The main feature that lends originality to the game is the addition of the "Chaos Legion", which are supernatural creatures that fight alongside the player.

While legions are summoned, Sieg Wahrheit (the player character) is unable to run and has weaker melee attacks.

Legions can be controlled to a degree: their tactics can be switched between offensive and defensive, and players can issue orders for them to attack immediately.

At first, Arcia mentions that the Maidens were in tough pursuit of Victor; thus, when she learns that Sieg is also searching for the same person, she decides to tag along.

Instead of killing her, Victor stops abruptly and regains control; a flashback then reveals the truth of the past: Three years before, Sieg, Victor and Siela were instructed by the Order to reseal the demon Azrail—discovering that the Order actually planned to use Azrail's power for world dominance, but realized that it was too powerful to contain.

In his uncontrollable rampage, he almost killed Sieg, but Siela stopped the final blow, and Victor drove his sword straight through, piercing her chest.

Azrail is then released and fights Sieg, not only in its own diabolical form, but also re-spawned in the figure of a darkened, corrupted Siela to intimidate him.

After all the chaos, Sieg mounts a tribute to Victor and Siela, and mourns over the loss of his two best friends, but Arcia cheers him up.
