Spurred by the flame raging in his heart, the Black Swordsman Guts continues his seemingly endless quest for revenge. Standing in his path are heinous outlaws, delusional evil spirits, and a devout child of god. Even as it chips away at his life, Guts continues to fight his enemies, who wield repulsive and inhumane power, with nary but his body and sword—his strength as a human.

Meet Sasaki, an overworked, middle-aged office worker. His days are marked only by the passing of more unrewarding corporate drudgery. Smoking helps take the edge off, but other than that, the only bright spot of his day is when he goes to the nearby supermarket and sees Yamada's smiling face. So, one evening after yet another exhausting day, he heads to the supermarket to find he missed Yamada's shift. Dejected, he decides to go find a smoking area but discovers there isn’t one to be found. Just as he’s about to leave, a girl in a biker jacket named Tayama asks him to join her at a secret smoking area!
