Isaac Husbando

Isaac, also known as Black Sword Isaac, is the guild master of Black Sword Knights. He is a Human Guardian-Gladiator and a member of the Round Table Alliance. Prior to the Catastrophe, he was a carpenter. His real name is Araki Takafumi, and he at one point assisted the founder of the Kahoku Construction Company, Miyagi prefecture. Isaac is a rowdy person who enjoys fighting, taking comments from his guild members like "You're really naggy, Commander," and "Chief is an idiot" in stride and treating them like compliments. Though he is easily irritated when people don't immediately agree with his views, he is not unwilling to listen to others. Early on, Isaac is antagonistic, elitist, and proud. Even before the Catastrophe, his arguments with Woodstock W over his elitist policies culminated in Woodstock leaving the guild, and Marielle wonders if "he just enjoys excluding others." He regarded People of the Earth as NPCs with no minds of their own and bought EXP Pots from Hamelin despite knowing the guild's cruel methods. He grows out of this unbecoming side of himself after the Round Table Alliance is established, and reveals that his gruff demeanor hides a thoughtful side. His aggressive policies in the aftermath of the Catastrophe were meant to keep his guild members motivated and distracted from the uncertainties of their current situation. Despite his negative initial impression of Iselus, he quickly came to respect how hard Iselus worked to become a suitable successor to his grandfather. He appears to respect those who accomplish things through their own effort, and strongly disapproves of Eins' more communistic approach to Akiban affairs.
