Volume Seven — read in one sitting. If you can.
A horror manga publisher that does not blink.
Spiral is a publishing platform for horror manga, occult zines and slow-dread short stories. Fine-line panels, paper-white pages, captions that wait one beat too long. We do not flinch when readers refresh.

Everything you need to ship
One platform, every primitive. Replace a half-dozen tools and ship in an afternoon.
Fine-Line Reader
A reader tuned for hairline ink work. No compression artifacts at any zoom. Crosshatch reads like crosshatch. Whites stay paper, not screen.
Slow Reveal
Schedule panel pacing per chapter. Readers cannot scroll past a panel until it has been seen. Some pages choose to never end.
Caption Engine
Hand-set narration boxes with the typographic care of a final printed volume. EB Garamond, Special Elite, your custom fonts — at print-quality kerning, not screen-quality.
Archive Mode
Older chapters sink deeper into the archive. Index pages render as nested catalogues — readers find old stories the way they find old letters in an attic.
Reader Marks
Save and annotate panels. We do not track which panels you reread at three in the morning. We do not need to know.
Silent Pages
Wordless pages render in single-panel mode without UI chrome. The page becomes the screen. Most stories find their voice this way.

Questions, answered
Yes, but the platform is tuned for black-and-white fine-line work. Color manga reads correctly but loses Spiral's defining grain. We recommend the Witness tier for color work — it lets you upload print-quality TIFF without compression.
