death on your heels, home left behind

Rengoku Kyoujurou wakes from death to the scene of countless corpses in front of him.

(Or: he dies by the hand of an Upper Moon, protecting a boy who had managed to defeat and save the train that lay behind them. He dies with only one regret: that he leaves behind his new Tsuguko, his father, his younger brother.

He dies and then he wakes up.)
