Hirohiko Yokomi

Hirohiko Yokomi is the travel-writer, who turns out to be a huge train-fan. He has a lot of energy and passion for trains, and sometimes girls, but also micro-manages all their trips, planning every detail down to the second. He cares mostly about following the schedule and successfully achieving his planned goals (e.g. visiting all stations on a line in a completely bizarre order to accommodate infrequent trains).
