Background / History

Diavel was a Beta Test player who remained in the Town of Beginnings after Sword Art Online became a death game. Rather than leaving the Newbie Players behind, he spent his first day helping them develop without revealing his Beta Tester status. His initial group eventually expanded into two full parties. 75

He led these squads through the First Floor labyrinth with disciplined switching tactics, reaching seventy percent exploration through his own team's efforts and ultimately discovering the First Floor boss room. 73 76 83

Diavel convened the First Floor boss-strategy meeting, organized the raid's party assignments, and commanded the battle against the Goblin Lord. During the boss's berserk phase, however, he attempted to secure the final hit and the limited Midnight Knight Coat. The Goblin Lord nearly killed him with Floating Boat before Xiang Kong intervened and saved him. 83 87 88

After surviving the raid, Diavel admitted that he had arranged efforts to stop Kirito from obtaining the final hit and its limited reward. He later tried to pressure Kirito into surrendering the Midnight Knight Coat, causing Xiang Kong to delete him from his Friend List and end their friendship. 88 90

Diavel subsequently founded the Knights Alliance, which became the largest guild in the game. He continued pursuing a first-clear advantage over rival guilds, especially after learning that Xiang Kong had joined the Blood Alliance. 92 110

He abandoned sword-and-shield combat to become a Spear User, purchasing the limited unique Sun-Piercing Spear for 400,000 Kael in preparation for the Lord of Thousand Serpent Castle. 122 123 142

Appearance

Diavel is a blue-haired Player who initially fights with a one-handed sword and shield. 73 87

• Blue hair, visible while commanding his teams from the rear. 73
• Usually carries himself with a warm smile and polite demeanor when meeting other Players. 74
• Later changes from sword-and-shield combat to a spear-focused build. 122

Personality

Diavel is charismatic, composed, and highly attentive to danger. When Xiang Kong approached his teams alone in the labyrinth, Diavel remained wary of the possibility that he was a scout for criminal Players, but listened to his explanation and judged the situation rationally. 73 74

He leads through clear commands rather than authority alone. He defended Xiang Kong from the “hunter” rumor by explaining the lack of evidence behind it, and his teammates trusted his judgment because he had previously helped them. 74 75

His leadership is complicated by personal ambition. Diavel's desire for the Midnight Knight Coat led him to manipulate the First Floor raid and later challenge Kirito publicly for the reward. Even after losing Xiang Kong's trust, he resolved to prove through future actions that he was not selfish. 88 90

Abilities & Skills

Raid Command

Diavel specializes in coordinating large groups in labyrinths and boss battles.

• Directs squad rotations, vanguard positions, and recovery periods under pressure. 73 87 142
• Employs switching tactics that allow his two squads to defeat Goblin Spearmen without taking injuries. 73
• Consults his members before extending exploration rather than deciding unilaterally. 79
• Led the Knights Alliance in attempts to secure first access to boss rooms and later Floors. 110 120 122

One-Handed Sword and Shield Combat

Before changing weapons, Diavel fought as a one-handed sword user with a shield.

• Uses the Guard Skill Slanting Toss, which blocks an enemy Sword Skill and inflicts stagger without a damage bonus. 87
• Attempted to use Slanting Toss against the Goblin Lord's katana technique, but was overwhelmed by its speed before the skill could activate. 87
• Abandoned this combat style in favor of spear use before the Seventh Floor. 122

Spear Combat

Diavel became a Spear User to make use of a key boss-raid weapon.

• Purchased the Sun-Piercing Spear through Argo for 400,000 Kael. 123
• Used the spear in the raid against the Lord of Thousand Serpent Castle. 142
• Its revealed trait, Blood-Deep Grudge, increases skill damage and effects by 200% against the Lord of Thousand Serpent Castle, while providing a smaller increase against other targets. 142

Equipment / Weapons / Items

• Sun-Piercing Spear — Limited unique spear purchased for 400,000 Kael; its Blood-Deep Grudge trait is particularly effective against the Lord of Thousand Serpent Castle. 123 142

• Midnight Knight Coat — A limited boss reward Diavel sought because of its rarity and long-term usefulness; Kirito obtained it instead. 88 90
