Humanity and Paper Balloons

Unno, a masterless samurai, has been supported financially since his father's death by his wife, who makes small paper balloons. He hopes that Mouri, his father's former master, will hire him after being given a letter from Unno's father. Unno's neighbor, Shinza, a hairdresser by trade, is under constant threat by gang members after running gambling dens on their territory.
