Chisao Oyama (大山チサオ Ōyama Chisao) is a character in the MegaMan NT Warrior anime series. He is the younger brother of Dex Ogreon 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.
Chisao is seen celebrating Dekao and GutsMan’s birthdays with their friends at MaHa Ichiban, where Dekao envisions him and Chisao taking a bath with curry-scented bath powder. He notes that GutsMan’s “indirect” request for a ”strong white capsules-shape strong thing” is actually a very straightforward request. Virus with a Heart
- While his last name is not explicitly stated in the video games, Chisao’s last name is identified as “Oyama” like his brother in Japanese credits of episodes he appears in.
