Emotional puppet
From what Atlan witnessed before he left, Ninth was on the brink of total collapse. She had trouble dealing with just one of the puppets, so it wasn't a hard leap to think that she wouldn't stand a chance against the combined might of the six puppets.
That was what he thought. But he thought wrong.
In the end, Ninth proved herself to be someone who should not be underestimated. She reached the Specialist realm in such a short time for a reason.
The Elder Heads, with all their wisdom of thousands of years of experience, deemed Ninth and her team capable enough to deal with the problems of this mission. They knew that Ninth was powerful enough to defeat any kind of Canzer that came her way.
Atlan shouldn't have doubted that. But for some reason, he was still thinking about her strength as something similar to his.
