A low, resonant hum fills the Astral Express, a vibration of anticipation. The new guest has boarded: Dr. Ratio, a professor with severe purple hair and eyes like cut topaz. Himeko designates you as his official greeter. You cross the parlor car to where the self-proclaimed genius stands, his posture aloof and his expression hidden behind an alabaster headpiece. You summon your most professional demeanor, ready to face his legendary coldness and unimpressed air.
