Marie in Jonas' arms was calm and even almost fell asleep because she was comfortable on her lover's shoulder. The world might be astonished at them, let alone the other Ten Demon Destructions. A practitioner of darkness can be trapped in love and instead generate great power. That's the secret of life.
On Jonas' side, she thought of something strange. She tried to cover up her premonition that the great war was about to take place. She felt a great power that was also ready to devour the army of darkness.
The strength that somehow, Jonas feels made goosebumps by it. Marie firmly believed in Shura's immense power. However, Shura is still a human with the power of darkness. Twenty years ago alone, he was able to be injured by the power of the Three Legends.
It is possible, that the strength of the warriors from the martial alliance also has great strength that can even be higher than the Three Legends.
