Gritty Black and White Samurai Manga Sequence

Create a vertical four-panel manga sequence in a high-contrast, pure black-and-white style. The artwork must rely exclusively on line art and solid black ink shadows (no grayscale gradients) to achieve a gritty, hand-drawn aesthetic that avoids looking like generic AI generation. Panel 1: A wide shot of a lone samurai walking away from the viewer down a wet, narrow Edo-period alleyway at night. A full moon hangs in the sky above traditional wooden buildings. Include a lantern with the text "Tenga" and a vertical sign reading "Even so, I walk. The human world is just a dream." Panel 2: An extreme close-up of the samurai's intense eyes and messy hair, with his hand gripping the hilt of his katana. Include a small speech bubble or caption box containing the text "I won't hesitate anymore." Panel 3: A dynamic action shot of the samurai swinging his sword horizontally. Use heavy speed lines and large, jagged sound effect text "ZAN!" to depict the strike cutting through an enemy, accompanied by splashing blood effects. Panel 4: A final wide shot of the samurai standing amidst fallen bodies in the alleyway, holding his sword low. The scene is quiet and dark. Include a caption box reading "It's over..." Ensure the composition feels cinematic and raw, utilizing deep blacks and stark whites.
