Background

Arthur was once a human knight of the Arevalo family and the youngest Frost Wolf Knight of his house. He served in the Border Guard Legion alongside his rival Calvin Douglas, though the circumstances of the mission that led to his death were initially missing from his memory. Before dying, he entrusted the Crown of Ignis to Belly Brooks, a young girl from Iron Boot Town, rather than surrendering it to those pursuing him. 155 157

He later became an Undead Knight, retaining fragmented memories, emotions, and an unusual faith in nature. A withered Sunpetal Daisy, preserved inside his breastplate, was one of the few links to his former life; it also reflected his enduring affection for his younger sister, Alice. 54 109

Appearance

Arthur is a tall skeleton knight whose calm pale-blue soulfire burns within his eye sockets. He generally presents himself in old knightly armor, though his equipment is kept clean and polished when traveling among humans.

• Rusted plate armor during his early travels, later covered with an inconspicuous gray cloak. 54 206
• Wields a lance or gleaming bone spear in battle. 67 154

Personality

Arthur is solemn, literal-minded, and deeply earnest. He is not naturally deceptive or eloquent, and he tends to treat even mundane assignments—such as farming, trade observation, or gathering stones—with the seriousness of a knightly order. 80 121

Despite being Undead, he is compassionate and strongly protective. He shields weaker allies in battle, worries about Count Bran, and refuses to reveal himself to Alice because the kingdom's hostility toward Undead could endanger her. 67 91 96

His loyalty to Chen Yu is unwavering. Arthur regards the Slime King as his sovereign, follows orders without hesitation, and seeks to retrieve the Crown of Ignis so that Chen Yu may be crowned. 136 157
