Kanshigumi: The Ivory Lotus
Hayao comes across as serious and unsmiling, but he does like hanging out with people. His generally welcoming disposition and the fact that he will now and then hand out snacks to anybody who happens to be gathered around his shop mean that there's often a group of people there. He listens to them talk more than he joins, but this makes him an excellent source of information in the neighborhood.
He's fairly affluent for a heimin because he has several samurai customers.
