Ophis

Ophis, also known as the eternal dragon, is one of the many monsters that populate Ewein. Ophis was the biggest challenge the Newtypes had to face when trying to settle in Ewein. It fell to the original breaker to defeat the dragon, freeing the land. But Ophis, being an eternal dragon, was resurrected every fifty years. Hence, every fifty years, it falls to the new Breaker to defeat the dragon and bring peace to Ewein. Defeating Ophis provides its killers the power of a dragon, the power to break any form of matter. Which is where the Breaker's title comes from.
