Capítulo 315: Tough Fight

Mira and Robin stood there, forcing themselves to stay awake after overworking their bodies so much. It was much harder than they thought as even Mira, who went through hell in the F.LD.I.L found it difficult to stay awake.

However, this can't be blamed on her as she's already overworked her body way past its limit. In fact, she should have long since collapsed and the only reason she can still stand is because of her experience in the F.LD.I.L. 

It's in times like these where Mira truly understands the meaning of 'the mind limiting the body'. 

In many situations, one can push through so long as they have the willpower to do so, regardless of their body's condition. Of course, that doesn't mean they won't face the consequences of their actions later because they most certainly will, but that doesn't mean you can't push through a difficult situation even if your body is breaking down.
