Each person carries his or her own PET, short for Personal Terminal, and each PET contains an artificial intelligence program called a NetNavi (or NetNavigator).

Lan Hikari is a boy who lives in DenTech City. Lan’s father programs a personal NetNavi for him as a present for graduating to the fifth grade. Lan’s new NetNavi’s name is MegaMan.
