Locke

Locke is the Warrior of the Human World, a human born with the spirit of a dragon and raised by Guardian Queian as a Drakon Kechatulla. Sent north to contain the Four Knights of the Apocalypse, he chooses to protect people in both worlds and becomes an ally of In-gong and the Demon King's children. His ability to combine swordsmanship, aura, and blessings from several gods makes him one of the coalition's strongest front-line fighters.

Biography

Warrior from the Human World

Before Locke appears directly, In-gong knows him through Knight Saga as the human-side protagonist: a temple-raised warrior who gathers companions, defends the Human World from invasion, crosses the Demon World's armies, and ultimately kills the Demon King. That record makes Locke a feared future enemy to a demon prince, but it describes a game route rather than the present Locke's settled intentions. Even within In-gong's recollection, Locke does not begin the war; he fights after the Demon World invades. (Chapters 2, 70, 136, 160, and 172)

The actual Locke is prepared for a different crisis. Born with a dragon's spirit and raised by Queian as the Human World's Drakon Kechatulla, he receives the elder dragon's blessing and travels north with Beatrice and Carlov when Queian foresees a battle that could spread across worlds. This departure occurs more than a year before the adventure In-gong expects from the game. After entering the Demon World, Locke senses another Drakon Kechatulla's power and divinity in the shattered night sky; curiosity and relief, rather than automatic hostility, shape his approach to the unknown Conquest Knight. (Chapters 143, 149, 172–173, and 191)

Northern Campaign and Sanctuary

Locke first acts within the Demon World as a concealed rescuer. Disguised as a sura, he pulls survivors from the ruined Sky Forest while his companions heal the injured. Queian has warned him that Conquest may still be dangerous and has ordered him to stop the coming war from reaching the Human World, so Locke initially watches from behind. He nevertheless rejects the idea that saving only his own world is sufficient and decides to protect the Demon World as well when possible. (Chapter 192)

That cautious independence guides his meeting with In-gong. Locke follows the royal expedition beyond the Northern Limit Line but maintains distance until the frost corps attacks. He then reveals himself by killing a frost worm, pressuring Yosarina, and preventing her escape so In-gong can finish her. Although Chris remains wary of a human warrior, Locke openly explains his mission and offers alliance to the Demon World's Drakon Kechatulla. The altered encounter replaces the game's expected human-demon opposition with cooperation grounded in the immediate threat from the Four Knights. (Chapters 203 and 207–210)

Against Shutenberg, Locke learns to fight beside peers rather than as the solitary decisive hero described in In-gong's memories. He, In-gong, and Zephyr break the arch lich's compulsion, receive strength from Conquest, and hold against curses and undead until the larger coalition damages the magic circle. Locke times his strike through Zephyr's fading attack, shatters Shutenberg's layered defense, and willingly leaves the finishing blow to In-gong—the first time he has entrusted that role to another. After In-gong collapses, Locke watches Zephyr's hesitation but judges his final rescue action rather than accusing him. (Chapters 212–217)

When the elder-dragon equipment warns of greater danger, Locke follows Zephyr toward the front and helps hold the Sanctuary against the red dragon. The Warrior's Sword leaves Locke to join In-gong when the true Drakon Kechatulla arrives, yet Locke continues fighting with another sword from Queian and expends all his aura and divine power to divert the dragon's attention. He spends the next three months guarding battlefields beside In-gong. When In-gong later offers the Warrior's Sword back, Locke refuses it, recognizing the new Demon King as the warrior who ended the crisis and asking for reciprocal aid if the Human World needs him. Their alliance ends the arc as friendship rather than a temporary truce. (Chapters 220–230)

Appearance and personality

Locke is a youthful human man described as plain rather than handsome, with blackish-brown hair, sky-blue eyes, and an innate charisma that draws attention. When he first reaches the Demon World, he wears dragon-scale armour and carries a sword filled with divine power; his bright, confident smile later becomes his most consistent visible expression. While operating secretly after the Sky Forest disaster, he instead wears ordinary red sura clothing as a disguise, which should not be treated as his permanent dress or species. (Chapters 173, 191–192, and 207–209)

He is confident enough to call himself mighty, yet his self-assurance is paired with steadiness, humor, and compassion rather than contempt. Locke rescues Demon World civilians his mission does not require him to save, stays calm when royal demons react suspiciously, and repeatedly uses jokes or a bright expression to ease tension. He respects Queian's warnings but makes his own moral judgment, eventually extending his protective purpose beyond the Human World. In combat he is fearless until the red dragon gives him his first experience of fear, and even then he continues buying time for the coalition. (Chapters 192, 208–209, 215, 222, and 225–227)

Powers and abilities

Locke is a high-speed swordsman who combines a dragon-born spiritual nature, advanced aura, divine blessings, and equipment prepared by Guardian Queian. His best demonstrations involve converting aura and divine power into enormous or numerous blades of light, disrupting supernatural enemies, and coordinating with fighters of comparable strength. Some of his most conspicuous techniques depend on the Warrior's Sword and must be distinguished from his innate reserves and training.

Dragon spirit and Drakon Kechatulla

Locke is born with the spirit of a dragon, in contrast to Zephyr's dragon-like flesh, and Queian raises him as a Drakon Kechatulla—the Human World's dragon warrior. The corpus calls him a miracle among humanity and a sword prepared against beings seeking destruction, but it does not explain the biological or ritual mechanism that produced his dragon spirit. Queian acts as both teacher and father, arranges Locke's training, blesses his departure, and equips him for the task of containing the Apocalypse Knights. (Chapters 46, 143, 149, 172–173, and 191)

His Drakon nature gives him a strong dragon aura and forms a sensory connection with other dragon warriors. Locke recognizes the distant power that splits the Sky Forest night as another Drakon Kechatulla and separately senses divinity within it. He later identifies In-gong directly, recognizes the world-spanning horn as the call of a Drakon Kechatulla, and feels an affinity with Zephyr and In-gong through their elder-dragon equipment. These perceptions reveal kindred power, not shared identity: Locke and In-gong remain distinct people prepared by different elder dragons and shaped by different worlds. (Chapters 191, 207–209, 220, and 225)

Aura, swordsmanship, and light constructs

Locke's innate combat foundation is a large reserve of aura combined with exceptional sword skill, speed, and timing. He can cross a battlefield quickly enough to keep pace with In-gong, meet barrages of ice blades directly, and read the intended movements of equally powerful partners without spoken orders. He channels aura through a sword to create light blades ranging from dozens of small defensive weapons to a single sword dozens of meters long. Those constructs can kill giant monsters, block massed undead, break magical barriers, and force the red dragon to divert attention. (Chapters 207, 212–215, and 227)

His strength is exceptional rather than limitless. Yosarina's frost armour survives the Warrior's Sword even after the surrounding cold is suppressed, Shutenberg and his undead force Locke into prolonged defense, and Shutenberg's soul torrent catches both Locke and Zephyr unprepared. In the final battle, Locke releases all his aura and divine power into one giant blade, but the red dragon destroys it. The attack still succeeds tactically by opening In-gong's route; it does not establish that Locke can defeat the dragon alone. (Chapters 207, 214–215, and 225–227)

Divine power

Locke grows up in a temple and receives blessings from several gods of the Human World. He activates divine power through prayer and can focus it into his weapon, producing seven lights whose presence alone drops nearby undead. He also uses divine magic to interfere with Yosarina's movement and destroys Shutenberg's erasing spheres with divine force. Unlike Beatrice, who is described as the particular beloved of one god, Locke's divinity is presented as several blessings working alongside his aura and swordsmanship. (Chapters 192, 207, 212, and 214)

Divine power is especially effective against undead and supernatural magic, but it is not an automatic victory over them. Locke still requires Beatrice's miracles, Conquest's reinforcement, Zephyr's magic, and the other magicians' damage to the battlefield circle before the coalition can overcome Shutenberg. The red dragon can also destroy a construct containing the full combined output of Locke's aura and divinity. No fixed prayer time, reserve measurement, or independent healing ability is established for Locke himself. (Chapters 212–215 and 227)

Warrior's Sword techniques

The abilities most closely identified with Locke are partly equipment-derived. Amita forges the Warrior's Sword from materials prepared by Queian, who fills it with powerful magic and gives it to Locke. Through the sword, Locke projects huge blades, creates dozens of aura-light swords for group defense, and uses its built-in super special move to release a destructive strike against Shutenberg. The weapon also carries Queian's power and can transmit warnings or feelings from him. Although Queian tells Locke to gather all six elder-dragon artifacts, Locke refuses to seize In-gong's pieces while they are allies. (Chapters 46, 73, 91, 207, 209, 214–215, 220, and 225–226)

These effects are not all innate skills belonging permanently to Locke. The weapon independently flies from him to In-gong at the Sanctuary, and In-gong later activates its hidden thrust, Beta; Locke is not shown using that particular technique. After the transfer, Locke fights with another powerful sword supplied by Queian that contains dragon magic, demonstrating that his aura, divine power, and core swordsmanship remain available without the Warrior's Sword. By Chapter 230 he deliberately leaves the named weapon with In-gong, so it is no longer part of Locke's latest equipment. (Chapters 225–227 and 230)

Judgment and coordination

Locke is accustomed to leading a small party whose members trust one another rather than commanding a national army. He keeps his group concealed, weighs Queian's warning against evidence from Demon World civilians, and chooses when observation must give way to direct intervention. His strongest tactical development occurs beside In-gong and Zephyr: he learns their rhythm during the Shutenberg battle, uses Zephyr's opening to break the target's defenses, and trusts In-gong with the final strike. (Chapters 160, 192–203, and 207–215)

His perception of people is useful but not infallible. Locke notices Zephyr's momentary hesitation before preserving In-gong, yet does not know whether attack or rescue was first intended and therefore stays silent. He is surprised by Shutenberg's last soul attack and feels fear against the red dragon for the first time. By the latest chapters, repeated battles let him and In-gong watch each other's backs and understand one another without explanation, but the corpus does not give Locke prophetic knowledge or perfect tactical awareness. (Chapters 215–216, 220, 225, and 230)

Relationships

• In-gong: Locke first knows In-gong as the potentially dangerous Conquest Knight and the Demon World's Drakon Kechatulla. Their actions against civilians and shared enemies turn caution into battlefield trust, and fighting across the northern and final campaigns makes them friends. They are parallel dragon warriors, not alternate identities. Locke ultimately leaves the Warrior's Sword with In-gong and asks for his help protecting the Human World in the future. (Chapters 191–192, 207–230)
• Queian: Queian is Locke's teacher, father figure, and the elder dragon who prepares him as the Human World's Drakon Kechatulla. Locke follows his warnings and mission while disagreeing with the idea that the Demon World may simply burn. Queian's continuing guidance reaches him through the Warrior's Sword, and Queian supplies a replacement dragon-magic sword after the named weapon transfers to In-gong. (Chapters 46, 143, 149, 191–203, and 220–226)
• Beatrice: Beatrice is Locke's saintess companion and one of the two trusted partners who enter the Demon World with him. She heals civilians, supports their pursuit with recovery magic, changes the northern climate for the frost battle, and helps break Shutenberg's magic circle. Locke searches for her when the battlefield is threatened and later remains attentive to her exhaustion. (Chapters 149, 173, 191–192, 203, 207–215, and 222–227)
• Carlov: Carlov is the Mercenary King and Locke's other principal companion. Locke treats him as one of the three people whose combined strength equals an army, jokes with him, and relies on his experience throughout their concealed journey and the northern campaign. Carlov remains beside Locke through the final battle. (Chapters 149, 173, 191–192, 203, 208–209, and 222–227)
• Zephyr: The game-derived future positions Zephyr and Locke as the opposing protagonists of their worlds, but their actual meeting occurs inside a common coalition. They discover an almost instinctive combat rhythm against Shutenberg, and Locke comes to regard the prince as a possible friend rather than a destined enemy. He remains observant of Zephyr's choices without claiming to know motives the evidence leaves uncertain. (Chapters 2, 70, 172, 212–225, and 231)
• Chris: Chris initially distrusts Locke as a warrior from the Human World and warns him against suspicious conduct. Locke answers without hostility, explains the purpose of his mission, and accepts that Chris's trust belongs to In-gong. Their relationship remains a guarded but functional alliance during the northern crisis. (Chapters 208–221)
• Carack: Carack meets Locke as the practical center of In-gong's group. His blunt humor punctures the solemnity of Locke and In-gong's first handshake, while his use of the King's Flag strengthens Locke against Shutenberg. During the crisis after In-gong collapses, Locke remains with the coalition while Carack helps organize the immediate response. (Chapters 208–221 and 230)

Items

• Warrior's Sword: Amita forges the sword from Queian's prepared materials, and Queian imbues it with magic before giving it to Locke. Locke is its owner and principal wielder through the northern campaign. At the Sanctuary it leaves him under its own power and enters In-gong's custody for the red-dragon battle. When In-gong offers it back in Chapter 230, Locke declines, judges In-gong the more fitting bearer, and deliberately leaves the sword with him. (Chapters 46, 73, 191–225, and 230)
• Unnamed dragon-magic sword: After the Warrior's Sword transfers to In-gong, Locke takes another powerful sword provided by Queian and uses it in the final battle. Its formal name, manufacture, and later custody are not established. (Chapter 226)
