Field Trip! is the girls' first adventure together. Masayo thinks she's seen an Imperial officer coming ashore at NINJA ISLAND - but everyone knows the rulers of the Jade Empire hate the ninja clans! She's tried to convince the staff and teachers but nobody is willing to listen to her, except Master Izawa (the history teacher). But even Master Izawa won't take any action unless Masayo can come up with some evidence.
So she takes off in the middle of the night, sneaking out of the school to track down this renegade Imperial. He proves easy to find, but difficult to pin down, and Masayo and the other girls end up with a shipload of trouble for their efforts.
This first issue is 24 pages of high-flying, ass-whupping ninja girl action. Sneaking out of school, into bars and not killing each other in the process, all of the girls have to pull out their best ninja tricks just to stay one step ahead of the feared Chamberlain, never mind Imperial officers with sorcery and minions at their command!
