It was still the middle of the night…
Not even an hour had gone by since the invasion over Arthur's residence started, and everything had gone downhill terribly.
Granite Crystal saw his children die one by one… and Amber… he did not know what happened to her, but she was having an intense fight against Noah, the leader of these monstrous subhumans.
Complete frustration and fear took hold of his entire self…
He needed to do something.
Anything.
He wanted to help Amber, to do anything for her…
But… he felt weak and pathetic…
After all, he was only D-Rank, weaker than his very children…
He had really thought that things would go fine.
He had investigated a lot, he had made sure to wait before striking, to prepare properly.
But even then, he was rash.
His children were eager to avenge Emerald, and so was he.
He let them go despite him thinking that there should be a few more days of waiting… he was simply desperate to avenge his son.
But everything went downhill.
