After the fight, the first thing that we did was confirm the casualties and the injured.
It looks like Minerva did her best, so the number of deaths in total was reduced to zero. Right, she managed to revive all those who died in the initial defense!
"Ahhh! It's the Goddess! Praise the Goddess!"
"Goddess Minerva! Please bless us!"
For some reason, Minerva became an idol to those who saw her "miracles." I guess the mix of advanced health science with a little skill application is no different than an actual miracle, so I don't blame them.
After the black knight's advent, it was fortunate that nobody moved too far from the island's center. As such, there were no deaths incurred from his indiscriminate attacks, and the last attack he released.
