• Supports multiple providers:

  • Shonen Jump+
  • Comic-Days
  • Comic-Action
  • & More...

• Downloads all pages of a chapter.

• Deobfuscates scrambled image blocks.

• Restores any missing transparency on the right side.

• Saves pages as PNG images inside a ZIP archive.

• Python 3.7 or higher

Dependencies are automatically installed with pip:

• requests
• beautifulsoup4
• pillow
• tqdm
• lxml
• InquirerPy

pip install laine

🔒 Make sure you have Python 3.7+ and pip installed.

Once installed, run the command:

laine

• You’ll first select a provider using an arrow-key menu.
• Then you’ll enter the chapter ID.
• The result will be a ZIP archive containing clean, deobfuscated PNG images of the manga chapter.
