Chisao Oyama (anime)

Chisao Oyama is a character in the MegaMan NT Warrior anime series. He is the younger brother of Dex Oyama who was attending a special school in Netopia while living with their father before coming to DenTech City towards the end of the first season. Unlike his brother, Chisao is brilliant, and is able to execute a Program Advance with GutsMan.EXE immediately after he operated him for the first time. After his initial appearance Chisao becomes a supporting character, often seen with Maylu Sakurai or Lan Hikari or paired with Rush.
