I know that I need to learn jutsus, but that doesnt change the fact that he cant use his arm. Well. If his not online he cant say anything so or we just leave this be or we ask for a judge.You can't say that he doesn't have enough time to perform the handseals needed to do the jutsu because he's wounded.
You need to somehow block the attack, not avoid it by saying he's too slow to perform it. You need to learn jutsus, Kiwii...
Oh, this was a friendly match, we dont need a judge. When he get back we can talk.
