Chisao lives in Netopia with their father. However, he keeps in touch with his older brother with e-mails nearly every day. He loves Dex so much that he even sometimes travel to Electopia to visit him. Chisao truly believes his brother is the best operator in ACDC Town[1].

Mega Man Battle Network 3[]
Chisao first appears in ACDC Town looking for Dex, after arriving from Netopia. He runs away crying if Lan Hikari defeats Dex in a NetBattle, and he celebrates Dex’s victory if the aforementioned Netbattle is won by Dex. He later goes with the Lan's class to Yoka and visits the zoo. Chisao is then kidnapped by a condor and trapped on a high voltage tower. He is saved when all the animals return to normal.
Mega Man Battle Network 4[]
Chisao appears shortly before the battle between Lan and Dex, then quickly runs in tears after thinking Dex was mad at him. Afterwards, it’s revealed he’s been kidnapped, making Lan and MegaMan.EXE go on a long quest solving riddles to find his whereabouts. It's revealed Chisao was the mastermind behind it all and he only pretending to be kidnapped. All the riddles was to waste time so Lan would be late and miss his match.
MegaMan NT Warrior[]
He still idolizes Dex but he is a supposed genius and can operate GutsMan.EXE better than Dex and can perform the Program Advance. Chisao is tricked into believing that the curry shop run by the ex-WWW is a base for aliens and is given NoodleMan.EXE to destroy it but they convince them of their identities and all the conflicts are resolved in the end.
He later becomes a reoccurring character in Axess, oftentimes paired up with Rush and joining Lan and Maylu on a few adventures. He becomes hurt and cries when Dex gains a tough-guy attitude and rebuffs him from his "training" with the ex-WWW members, even rooting for Lan and MegaMan during a NetBattle with GutsMan because of it. Despite his supposed genius, he still likes to partake in regular "kid" stuff, such as making sand castles in sandboxes and other activities.
