I could say the same thing to you and your fellow ZBoys about Kuzan.
There is a difference between truly believing that Shiryu is really weak and having this delusional belief that Shiryu is above Kuzan.
The latter which is you and your fellow ZBoys.
I don't think Admiral fans truly believe Shiryu is weak, but that right now it's fun to downplay him especially because for a while so many ZBoys tried putting Shiryu above Kuzan.
