Instructor Wang

Instructor Wang (王老師) or Old Man is one of the three professors working to resurrect Gyumaoh. He’s a tank top-wearing, decrepit old man whose very existence is a mystery. There are machine-like goggles installed on his face, and cords pierce his head. He is a youkai who usually plays chess with Dr. Ni and often snickers at Ni's snide comments made towards Professor Hwang.
