Name: Harumasa Asaba Gender: Male Birthday: July 19 A member of Section 6, a handsome and skilled archer. He is a master of Kyudo (essentially, he's great with a bow). While he appears aloof and relaxed, he isn't afraid to speak his mind even before superiors. He is a cynic who calls his friends and colleagues "idiots." He carries a listless atmosphere and is very perceptive. He occasionally fakes illness during work to apply for leave, but he actually suffers from a real disease: Ether Aptitude Decline Syndrome. He wears a yellow headband given by his master around his forehead. His outfit consists of a white shirt, black tie, black slacks, and a haori-like uniform draped over him. He wears sneakers. His eyes are yellow, and his hair is indigo and wavy. His primary weapons are twin blades that combine to form a bow. The choker around his neck is meant to hide injection scars from past experiments. As a patient of Ether Aptitude Decline Syndrome, he has issues with his lungs and heart, causing him to cough occasionally. He is popular enough to have a fan club and is nicknamed "Masa-masa" by everyone.
