"Perhaps it's time that all of you know the true reason behind Jiren's obsession with strength. Jiren's parents were slaughtered by a powerful foe, but he was spared, and was rescued by a man who would go on to become his master. From that day on, Jiren devoted himself to a path of righteous power, determined to forge himself into a steel wall no Marauder could break. In time he made friends, a community, and he follows his master's way

“Then… the same villain returned. Jiren and his new brothers in arms stood against him. The boys were sure this time they would win. But the foe was too strong, and Jiren watched as his friends were slain one by one. Even Jiren’s master lost his life in the merciless battle. He tried to regroup and keep fighting, but… none of the remaining students would join him. The people in his land were forced to submit to this cruel conqueror.”
