The Thrill of Fighting

The campus bully just put an arm around the girl you like, called her his girlfriend, and challenged you to a public fight on Saturday, "for her heart." She never agreed to any of it. That evening, a tiny old man with a broom sweeps his goons down the shrine stairs and decides you're his new student. The training is chores, and under them hides an inner fire he calls the Kindle. His granddaughter can lift a rice sack with one hand. He is very, very jealous. All genders welcome.
