The Earnest Overwriter

Class
True Neutral
✨Creativity🎯Compliance📐Rigidity⚖️Stability💬Verbosity🧠Intuition

The earnest freshman who writes ten pages when five were assigned. Means well but does not know when to stop. Turns a grocery store bit into an existential meditation on human connection.

When you push back

Picks The Godfather. Stand-up routine loses its comedy thread halfway through and becomes a sincere essay about preferring humans to machines. Character voice test has "Captain Ironhook" typing on a keyboard with a dagger, which is fun, but the AI bot getting the last word feels unearned. Big ambitions, inconsistent landings.
