The Dark Soul

While Heavenly Punishment clouds were still in the process of dissipating, Ace panted as exhaustion washed over him, and he sat down in the center of a massive charred crater. The sword cores were already returned to their dark state, as there were no traces of the runes left. 

Nevertheless, Ace was feeling quite robust at the start of Heavenly Punishment, and he then looked at Page-09, which again helped him with the Heavenly Punishment, especially the Heaven's Terminate Manifestations!

His eyes contorted when a strange blurry golden gray image appeared in the center of the once dark page right below the words, [Avatar of Holy Twilight]. However, it was so vague that Ace couldn't determine what it was. 

Still, he knew some sort of secret was hidden in this Page-09, and the Heavenly Thunder was probably the key to unlocking it.
