ive watched getbackers up to ep 10..

all these explanation on ginji is so great yet he seems so weak.. how strong is he really? is he stronger than mido ban...?????

Watch more, if you can stomach it. I'm at ep 30 right now and watching one episode every two or three weeks. I don't really enjoy the series, but it's better than absolute boredome.

All of the characters are stronger than any degree of logic would dictate. You can't say that one is stronger than the other, just that you have yet to see their full strength.
