MegaMan NT Warrior

Set in the year 20XX, fifth-grader Netto Hikari receives a unique gift: his own customized Net Navi, Rockman. Although Rockman is small in stature and possesses a notably more responsible demeanor, the pair quickly forms an inseparable bond. Designed to assist operators from within their Personal Terminals, or PETs, Net Navis serve as digital companions and guides. In this world, children and adults alike participate in friendly Net Battles, sparring with their Navis to demonstrate their skill and prove their worth.
