Just ignore Captain and the rest of them. They're not the nicest bunch, especially when you dig yourself a hole like you have.
Just ignore them, don't even respond to them if you can, they're full of hot air.
The trick is to not feed their inflated egos, which is very tricky. {Them all flaming you is one way to make themselves feel important}
Best to completely ignore them, but try to follow the rules a bit more closely, will you?
Anyways, what exactly is the problem? For the sprite sheets, Gunfish should be in the sprite sheet Cent, and Midorin uses Guest in the first slot.
