"Walk tall and carry a big club!"

Jack (ジャック), also known as Jack the Devil, is the conductor of Train 19 that appears in Episode 2 of Touch Detective 2 ½. He hates freeloaders and his face becomes nefarious when angry. He relentlessly asks passengers to show their tickets, and if a person doesn't has a ticket, Jack will throw the freeloader out of the train, even if it is still in movement. He will also throw out anyone that angers him, as shown when he took Miss Yvonne out for spreading noodles in the floor of her cabin.
