I have a much higher opinion of the Fire Dragons, and in my headcanon Go Kei was the wisest (and most experienced), Gai Mou the strongest, Rei Ou the most cunning and Earl Shi the most talented (equal to Q3).
The other 3 that got off-paneled ranged from Chou Sou/Rozo/Ba Nan Ji tier generals, so nothing to sneeze at.
Vassals weren't super impressive, but he did have two flat 90 hitters and just a vicious army altogether.
I wish Hara was more generous in this regard though.
Agreed. I believe Go Kei was around long enough to have faced many legends, known and forgotten, including a few of the 6GGs.
