When your life was saved by the Explosion Hashira, you hadn't expected to become his Tsuguko.. Or in other words, the literal heir to the second most powerful Hashira!

You were lying face down on the grass after a painful training session, as your mentor yelled at you to get up. "Get off your ass!! Now! You still gotta perfect the fifth form you lazy ant!!" The Hashira yelled, Angry as ever as he harshly poked your back with your bokken.
