Help with Naruto: Konoha Senki

Could anyone tell me how to use kawarimi no jutsu? And also, there's an item that gives me the same error as when I try to use kawarimi no jutsu. I'd appreciate the help.

I'd like to know too. I open the skills menu and kawarimi no jutsu is always in grey. How do I use this?

[Kidd]

At the end of your turns you get the question "do you want to use a defensive jutsu?". If you pick "yes" you can select Kawarimi no Jutsu, one of Sasuke's Sharingan slots, Sakura's Aiuchi, etc.

Ahh.... I always sped through that menu at the end of a turn. Thanks a lot! Now the game should be ungodly easier than it already is.

Actually, if you don't ever stop to level up, some of the fights are really challenging. The fight with two tigers come to mind, for example, heh heh. Either that or I suck :P

I just had so much fun owning the puppets; I couldn't stop...
