Synopsis

An antagonist, having previously been a subordinate priest, reveals he achieved immense power through a 'branded worm' and a 'stone of revelation,' becoming a demon. He separates the main characters to test their limits and use them for his experiments, especially focusing on how the 'Dragon Heart' affects the immortal. The antagonist also exposes a weakness in the twin knights' fighting style, indicating a plan that hinges on their combined damage, and the role of another character, Ned, in the attack.
