Guy Crimson

Guy Crimson is one of the oldest and most powerful Demon Lords in the world of That Time I Got Reincarnated as a Slime. As the first Demon Lord and one of the Primordial Demons (the Red Primordial), Guy has existed since the dawn of time and possesses unfathomable power. He resides in the frozen continent and serves as a mediator among the Demon Lords through the Walpurgis Council. Despite his immense power and age, Guy maintains a playful and somewhat capricious personality, though he takes his role as the balancer of the world seriously. He is one of the few beings capable of fighting True Dragon Veldora on equal footing.
