After witnessing their strength as a team battling against the Abyssal Shades, Raiden decided to join the crew, and they had accepted his entry... more or less. Sirius was the one who officially welcomed him, but he was sure the other two wouldn't mind.
Sirius nodded to everyone. "Alright, everyone. We move on to the next level." Xander and Aurelia nodded as they began to regroup. Suddenly, Raiden's estranged voice broke through. "Where are you guys going?" he asked, raising an eyebrow.
Sirius turned back, looking confused. "Um, outside this cave. We're moving on to the second level," he explained.
Raiden shook his head. "Yes, we're moving on, but aren't you forgetting something?"
His three comrades frowned, oblivious to any task they were supposed to complete. Raiden sighed, shaking his head as he pointed at the three of them. "Aren't you guys going to harvest the cores from them?"
