A while before.
Ryu was leaping towards the Ancient Hydra. He didn't know if he could scratch its scales, nor did he knew what to do against a powerful opponent. He let his instincts took over.
But once he was near the Ancient Hydra, he realized how minuscule of existence he was. Compared to it, it could smash him to pieces if it so desired.
Fortunately, the Ancient Hydra didn't seem to notice him until he was near the cave. With his gauntlets in his hands, he was about to attack its massive body with all his strength when a voice called out to him.
'You've come.'
Ryu blinked. The voice came inside the cave, and he forgot about the Hydra like he was under some kind of spell.
'Come inside.'
Ryu snarled and shook his head. He reminded himself that Cecily and the others were still fighting the Ancient Hydra, and he had to help them.
