• Cain informs Orsted about Eris, and Orsted reassures him that she will not interfere with the plan, apologizing for previously testing Cain.

• Eris becomes increasingly affectionate toward Cain, hugging him and secretly keeping one of his white robes because she enjoys his scent. Rudeus discovers this but is threatened into silence.
• Rudeus tutors Eris in reading and writing while Cain joins the lessons to learn the Human Race script. Cain progresses rapidly and learns most of the material in little more than half a month, while Eris struggles badly and repeatedly falls asleep.
• Cain also helps teach Ghislaine and Auber. Auber learns quickly, but Ghislaine has the same difficulty as Eris.

Chapter Summary: “The Sharpest Battle Aura”

Key Plot Points and Events

• Cain notices that Eris’s attachment to him has become unusually intense, but he chooses to interpret it as ordinary devotion between a disciple and her master. He comforts her physically and continues treating her affectionately.
• Since Eris still cannot use Intermediate Fire Magic because of her limited mana, Cain changes her goal. He challenges her to learn Lower Healing Magic and Lower Detoxification Magic instead:
  • Learning Healing Magic will earn her one gift.
  • Learning both spells will earn her two gifts and one wish.
• The next morning, Cain begins teaching Eris about different forms of Battle Aura.
• Rudeus returns exhausted after spending the previous night with several women. Cain heals him with Advanced Healing Magic, but Rudeus’s blissful, suggestive behavior disgusts Cain and reinforces Eris’s dislike of him.

• Impressed by the dazzling display, Eris declares that she wants to learn Cain’s Battle Aura. Cain asks her to identify her deepest desire, ending the chapter on a moment of emotional and martial significance.

• Cain and Rudeus: Their relationship remains friendly but comedic and unequal: Cain supports and heals Rudeus, while privately judging his behavior.

Significant Themes

• Mentorship and responsibility: Cain prepares Eris for a future in which he may not be present, showing that true teaching involves independence rather than permanent reliance.
• Admiration and imitation: Eris wants to follow Cain’s path in both swordsmanship and Battle Aura, reflecting her intense respect and personal devotion.

• Contrasting lifestyles: Cain’s disciplined mentorship and sense of duty contrast with Rudeus’s pleasure-seeking behavior, creating both humor and tension between the characters.

Chapter Summary: “Teaching Eris Battle Aura”

Key Plot Points and Events

• Cain explains that Battle Aura, like swordsmanship, is powered by desire. Eris identifies her central desires as defeating Cain, remaining by his side forever, and protecting their companions.
• Cain demonstrates his unique, highly destructive Battle Aura technique, Demon Light Slash, which combines Battle Aura with mana and obliterates distant targets and part of the training grounds.
• Although Eris cannot learn Demon Light Slash because of its enormous mana requirements, Cain teaches her his offensive, blade-like Battle Aura. He warns that it offers little defensive protection, but Eris readily accepts the risk because she prefers overwhelming attacks.
• Cain begins Eris’s training by having her split extremely hard Demon Granite with a wooden sword coated and shaped with Battle Aura. He demonstrates by cutting a massive rock in half with a Battle Aura-enhanced strike.
• Eris commits herself to mastering the technique and earning the title of Sword King. Auber and Ghislaine secretly observe the training, curious despite being unsuited to Cain’s style.
• Over several days, Eris trains intensely and ignores noble gatherings. Philip accepts her decision, abandoning the possibility of arranging a political marriage because Eris’s attachment to Cain is obvious and Cain’s status is extremely influential.
• During combat practice, Eris defeats Rudeus in an instant after Cain warns him not to lose focus. Cain becomes concerned that Rudeus’s poor instincts and habit of overthinking could get him killed.

Character Developments

• Philip: He accepts Eris’s rejection of noble social events and appears to respect her commitment to Cain, especially given Cain’s political and martial influence.
• Auber and Ghislaine: They show admiration and curiosity toward Cain’s unusual Battle Aura by secretly watching the training.

Significant Themes

• Desire as the source of strength: Cain presents personal desire as the foundation of both swordsmanship and Battle Aura. Eris’s powerful ambitions make her especially suited to the technique.
• Offense versus defense: Cain’s Battle Aura emphasizes overwhelming offensive power at the cost of protection, reflecting Eris’s reckless but decisive fighting style.
• Dedication and talent: Mastery depends on both natural aptitude and persistent effort. Eris’s determination suggests she has the potential to master Cain’s method.
• Love, loyalty, and protection: Eris’s desire to stay with Cain and protect her companions motivates her training and influences her rejection of political marriage.

Chapter Summary: “Training Rudeus”

Key plot points and events

Cain intensifies Rudeus’s combat training after recognizing that Rudeus’s poor instincts and tendency to lose focus could get him killed. Cain battles him directly, immediately breaking Rudeus’s wrist when he freezes, then heals him with Saint Healing Magic. He explains that such harsh treatment is meant to prepare Rudeus for the dangers of traveling to the Three Magic Nations with Sylphiette. Cain demonstrates that he is equally strict with Eris, whose repeated injuries have helped her develop strong survival instincts.
Over the following months, Rudeus makes only limited progress. He remains unable to consistently avoid Cain’s opening attack and struggles against Eris, who combines North God Style techniques, throwing knives, smoke bombs, and combat experience to disrupt his magic. Cain ultimately advises Rudeus to study the North God Style under Auber, as its adaptable principles suit Rudeus better than the Sword God Style.

Character developments

• Rudeus: Confronts his lack of combat ability and realizes that magical talent alone cannot protect him. He is frightened and discouraged but continues training because he wants to survive his journey and reunite with or accompany Sylphiette. His insecurity becomes apparent when he asks Cain whether Cain dislikes him.
• Cain: Reveals himself as a severe but genuinely concerned mentor. His brutality is motivated by a desire to correct Rudeus’s fatal carelessness before Rudeus faces real enemies. He eventually reassures Rudeus that he does not dislike him and acknowledges that Rudeus is working hard.
• Eris: Demonstrates the results of years of harsh training. She is far more battle-ready than Rudeus, nearing Saint Rank and using unconventional tactics effectively. Although she feels some sympathy for him, she refuses to excuse his mistakes and reacts defensively when Rudeus questions Cain’s feelings.
• Rudeus and Eris as students: Their contrasting strengths become clearer: Eris excels in practical combat, while Rudeus is stronger in magic and written knowledge but lacks instincts and discipline under pressure.

Significant themes

• Survival and vigilance: The central lesson is that carelessness, hesitation, or distraction in battle can result in death.
• The limits of talent: Rudeus’s exceptional magical ability does not compensate for his weak combat instincts or lack of experience.
• Harsh training as protection: Cain’s cruel methods are framed as necessary preparation for a dangerous world rather than punishment.
• Different forms of aptitude: The chapter emphasizes that the best style or path depends on an individual’s nature; Rudeus may benefit more from the flexible North God Style than the direct Sword God Style.
• Mentorship and concern: Cain’s strictness hides genuine care, while Rudeus’s fear of being disliked shows his emotional vulnerability and need for reassurance.

Character interactions

Cain repeatedly confronts Rudeus’s carelessness and forces him to continue despite fear and pain. Eris serves as both a comparison and a training partner, showing Rudeus the standard he must reach while using her own combat skills to challenge him. Cain’s explanation of Eris’s injuries helps Rudeus understand that his treatment is not personal. The chapter ends on a softer exchange in which Rudeus voices his insecurity and Cain reassures him that, despite his shortcomings, he recognizes Rudeus’s effort and does not dislike him.

Key Plot Points and Events

• Cain and Rudeus spend the morning researching magic together. Rudeus has developed another composite spell: a high-pressure Fire Magic core compressed inside an Earth Magic shell.
• Cain acknowledges Rudeus’s exceptional magical talent and quickly learns many of his chantless spells. In return, Cain gives Rudeus two Asura Gold Coins for each spell, despite already having compensated him generously with valuable magical tools.
• Rudeus has become more emotionally stable and focused on magical research, largely because his desires and needs are being fulfilled. He is also less distracted by his former lecherous behavior.
• During combat training, Cain repeatedly targets Rudeus first in the four-against-one battles. He explains that, despite being physically weaker than Eris, Ghislaine, and Auber, Rudeus is the greatest threat because a chantless mage can unleash devastating magic without warning.
• Cain emphasizes that backline mages must be eliminated early in battle, especially when they can cast high-level spells instantly. This explains why he has pushed Rudeus to improve his physical reactions, mobility, and combat skills.
• Rudeus realizes that he had misunderstood Cain’s strict training methods and apologizes. Cain reassures him that his harshness came from wanting to keep him alive.
