Raiden and the other kids from his age didn't think that their first actions in that conflict would be to help so many wounded people. They also saw a lot of people dead and many people dying… some of them had been hit by cannonballs and survived, only to suffer for a while.
"I guess since I lived a peaceful life in the village, I forgot that this world is really a shitty world that slaves kids and make them work to death before they can reach adulthood," Raiden thought when he saw the sun setting."
Although they managed to help a lot of people, there was still a lot of work to be done in the port. Iri looked exhausted since she used all of her energy time and time again, but she still kept going working on the wounded, so Raiden couldn't fall back either.
