Ego Eris: the Swordman's Blood

The year is 75 AD. In the ancient Roman Empire, a criminal - Aaron - is imprisoned in the amphitheater. Used not only for gladiator fights but also for the execution of criminals, the amphitheater was the most important entertainment facility for the citizens. However, Aaron, a "criminal who deserves to be killed," is burdened with a deeper sin than anyone else; he must never be killed, he must never die. This is the story of a man obsessed with revenge, and his continued resistance to his "fate." A stunningly drawn historical spectacle begins!!!
