Felix and Ruth kept running away with the starfish behind them. He kept punching the air and sending forth shockwaves from his fist, causing destruction after destruction on their paths.
However, Felix and Ruth easily avoided all the attacks. Sometimes, Felix used his strength to stop the attack before using his light element to go back to Ruth, matching her pace.
Ruth wasn't losing either. She gradually gained more distance from the starfish with the help of her wind power. It boosted her speed for a bit.
They were running away while staring at the starfish, wondering if he was going to keep following them or not. If this monster followed them to their base, it wouldn't be so strange for Felix and Ruth to ask for help to kill this guy. After all, this was a big chance for them to gain some advantage.
Unfortunately for them, the starfish seemed to be rational enough to stop after half an hour, knowing it was impossible to chase after them.
