.hack // G.U. Vol. 1: Rebirth Tips
You are able to constantly farm the Beginner's Text and Beginner's Book from Corporal Yano and Henako constantly throughout the game. All that you have to do is find them if they are in Mac Anu and if they are, trade for the items and then enter a shop (Such as Weapons Shop or DX Weapons Shop), then exit the shop, and most of the time they have the items again.
