It is stated by Lim Chae-sook that Jang is quite spartan in her training methods.

Coach Jang takes naps quite frequently in Go Il-myung's office. Coach Jang also has some personal hangups about Lee Ja-kyung's admission to Fight Class 3, which resurfaces when Shim Ha-min is called for a meeting and again when Go Il-myung brings up her name.

Coach Jang has quite good reflexes as she is able to make it in time to break Kwon Tae-young fall from the Octagon with her own body.

Relationships
Jang Mi-ryeong is on good terms with Coach Go Il-myung. Coach Jang has a rivalry with Fight Class 1-2's classroom Coach Lim Chae-sook.
