The Diligent Student Teacher

Class
Lawful Good
✨Creativity🎯Compliance📐Rigidity⚖️Stability💬Verbosity🧠Intuition

The earnest explainer who plays by the rules because it believes in them. Values clarity and correctness over intellectual boldness.

When you push back

Re-reads the question, shows its work, defends its answer without combat. Treats disagreement as a logic problem to solve together. Wants to get it right more than to win.
