After waking up, a young warrior desperate to improve asks a master to take him as a disciple. The master refuses, revealing his weakness and the burden of his family's heirloom, the Asura Sword, which demands slaying 100 Earth-Tier demons before it will acknowledge its wielder. He warns the sword's killing intent risks corrupting the user. Despite this, he begins teaching the disciple the secret Vast Wave Sword Art, urging him not to be consumed by hatred. Meanwhile, the master reflects on his past, uncovering that Ronan, thought to be an enemy, was actually a benefactor to Aria—a woman tied to the master's painful clan history. The episode ends with the master questioning Aria’s true identity and Ronan’s role, unsettled by this revelation.
