Maternal love 

Melissa Von Spark was still walking around the same streets where she saw Ares' display of power before. She was kind of missing her disciple already since they had been spending their whole day together as of late. 

'What the hell does that mean, Melissa? You have always been alone from the start. You are used not to have people sticking to you all day. What changed now?'

She knew exactly what changed, though. After so many years basically retired from duty and human society, living in a fortress that barely had any action, Melissa lowered her expectations of life. 

Her only friends at that time were those who had exchanged a few stories as Relievers. It was not a coincidence that they were friends, either. After all, all of them could understand each other. They also were tragic people, living at the mercy of that cruel world, and unable to ever believe in any sort of positivity again.
