The victim of a railway accident that left him orphaned—which occurred near the end of the age of rail closures—he set out to repay the family that adopted him, after pulling out of a state of depression that sapped his will to live. Often emotionally despondent, he is viewed by some as being very logical, and by others as lacking humanity. He left his adoptive hometown of Ohitoyo to go to college but has returned upon hearing that there are plans to build an aircra factory there. He awakens Hachiroku by accident and is then forced to confront his past with the railways that took his family.
