Romani used to be the Chief of Chaldea's medical team, but after the explosion accident, he has been acting director of the organization. Also known as "Dr. Roman."
While he is rather weak struck and bit wimpy, he’s a reliable person who doesn’t mind lavishing labor to make the best of each trip (ray-shift?) of Fujimaru and his team.
He is a fan of the virtual idol, "Magi☆Mari."
