One of the Seal Dragons that was allowed to return to the surface temporarily, if meant that they could gain any advantage over the invaders. He had his power sealed not because of a power he couldn't control, but because he is the servant of "Blockade". Because he was born without being blessed with power, he admired "Blockade", who came from the same hometown as him, for being declared the strongest warrior of their clan, and became his lone servant. He researched every form of ventilation and control that existed, so his master could control his magical power, but in the end, "Blockade" was labelled a dangerous entity, despite all his hard work. Though Blockade was not imprisoned, its body was sealed by a Class 1 Seal. Following his master and becoming a Seal Dragon, he has become very aware of the horror and usefulness of this power called "seals", and resumed his research. He will never give up. Not until the cursed dragons can exist in the world, accepted and unsealed.
The Seal Dragons
The generic term for the dragons who have been sealed and imprisoned by the direct order of the Emperor for various reasons. The degree and means of sealing are different than that of Dungaree. They are housed and imprisoned in a vast prison deep underground called the "Magma Prison", under direct supervision, with twice as many locks and seals as normal criminals. However, in order to counter the invasion of "Link Joker", several warriors were discharged from the prison temporarily and allowed to fight, with some of their seals weakened. As well, the stage of the seal is different which each convict.
