The group bid farewell to the Principal who was still in the middle of fighting before leaving the area.
On their way, Grey told them about his hypothesis.
"If what you say is correct, then leaving Teacher's side wouldn't be the best option," Instructor Blake said.
The Principal was the only one in the Sage Plane amongst the group. If they were to escape without him, it would mean that they would fall into the hands of these people since they could track them.
There's also the possibility of them having a hidden Sage Plane corpse lying in wait. A single one could easily wipe out the team.
Grey thought about it and couldn't refute Instructor Blake's words.
"So what do we do now, return to father?" Klaus asked.
"We haven't gone far from him, so going back wouldn't be an issue," Instructor Blake replied.
They turned to head back, but the sky above them suddenly went dark and a skeletal hand came out from the sky, heading towards the group as they tried escaping.
