Chapter 504 : Prison Break (1)

"Activate the alarm! A prisoner is breaking out!"

The leader of the squadron angels, the same one who captured Zodiak, ordered his subordinate before vanishing. Along with dozens of armed angels, he flew towards the 4th underground level of the prison. 

This place was a prison, the biggest and most fortified of its kind, in fact. It was situated right outside of Heaven, on a solitary and inhabitable planet called 'Lost Cause'. This prison had countless dangerous beings that tainted the history and caused irreparable damage to the world.

The deeper the level, the more powerful the criminals are. As they could not properly gauge Zodiak's power and only felt it from a distance, they threw him to the 4th level. The deepest level is, apparently, the 13th level, where, in the past, two of the Twelve were imprisoned.
