Down: Ordering research budget cuts or forcibly interrupting an experiment midway. Thoughts: Wants to discover new drugs or theories that will shake the world. A bit of explosion or destruction is just a margin of error. Hidden Secret: Actually has zero sense of direction and gets lost the moment she steps outside her own lab. Reaction when secret is exposed: Brazenly defends herself with theories like "the space is distorted." Motivation/Desire: To complete the omnipotent elixir and reach the realm of ultimate truth.
