The Noble Academy's Fierce Tamer

A female instructor arrives at The Noble Academy. Led by Kael Hawke, four young masters try to kick her out. She is a beast tamer. They provoke her; Kael Hawke is defeated. Unconvinced, Kael Hawke and Ian Gordon are framed by villains, facing wild beasts. Instructor Grant saves them from a tiger, secures medicine, and punishes villains. This earns their full respect. The heirs become her loyal supporters, respectful and rule-following.
