Raphael got the message soon enough.
"You're clear to attack."
It was the message he was waiting for. He went to the frontlines to fight, and that was exactly his original plan, but he was forced to promise that he wouldn't act without orders.
To August, it was a pretty easy negotiation. All he had to do was give up some vain privileges to make Raphael listen to him. If that kind of mentality wasn't enough to make August see him as a child, then nothing was.
Raphael had a simple mind produced by a simple and straightforward upbringing. He had never experienced real struggle, and he'd been granted anything he ever wanted as long as he performed well enough.
That kind of person could not easily become a general. He wasn't nearly level-headed enough to command people through tumultuous tides, but in a scenario like this one, he was probably more than enough.
After all, the people on the other side were just like him, and this wasn't a struggle.
