MegaMan: NT Warrior

Chisao's in Town! (1x54)

:

Dex's little brother Chisao is visiting from Netopia, but Dex becomes embarrassed when Chisao shows he's a better NetBattler than his big brother. Saburo, a noodle shop owner, gives Chisao his own NetNavi, NoodleMan, and tricks the boy into using him to battle WWW (who runs the curry shop Saburo competes with).
