True berserk occurs when a beast loses all sense of reason, let goes of its sanity, let goes their control over its powers, and just mindlessly runs wild and destroys everything or makes the reason for its berserk their target of obliteration.
The boy had faced this kind of berserk once and almost lost his life to the berserk creature.
He also met one of the most important persons in his life in this process but he definitely couldn't defeat that truly berserk being.
He couldn't do that back then, but now he was different.
He was stronger and had more equipment, strong weapons, and even some special powers.
He was confident that he could win against a creature like that one, though after a bloody fight, he was sure he can.
And if he could defeat that demonic beast, this pure one that had gone berserk and was one step lower than that one, was a definite easy target.
