Lore
Ningyo is a Cryptid — a rare, coastal merfolk recorded in scattered fishing logs and village lore. Seen at the edge of surf, it presents as a small, humanoid head and torso set against a tapered, fishlike body, skin sheened with iridescent scales. Smell: brine sharpened by a faint, sweet note like seaweed left to sun. Sound: a single, high keening — part bell, part childlike wail — heard most often at dawn or under a rising tide. Temperature: oddly warm to the touch, as if it carries the slow heat of a sunlit tidepool. Field notes emphasize its tentative curiosity, a slow, deliberate movement that reads as cautious rather than outright hostile; capture is rare and often followed in lore by violent weather or strange fortunes for those involved.

Field Notes
Observations
- Scattered, coin-sized iridescent scales caught in tide-foam or a solitary, bell-like cry at first light.
Encounter Advice
- behavior: Primarily solitary and crepuscular. Ningyo patrol rocky shores and inshore currents, surfacing at dawn or dusk. It inspects nets and floating debris with careful motions, and tradition records storms or bad luck when one is forcibly taken from the sea. It is not aggressively predatory; its actions read as defensive and investigative.
- interaction: Observe from a distance. Do not attempt to net, drag, or restrain. If one is accidentally entangled, cut lines and return it to the water promptly; aggressive handling is recorded in accounts as inviting sudden squalls or misfortune. Offer clear seawater and a small portion of fresh fish if you must engage — then step back. Record appearance and behavior rather than capturing.
- offering: A small bowl of clear seawater and a single piece of fresh fish or a strand of kelp set on drifting foam.
Abilities
- Flesh of Long YearsConsuming even a small portion of ningyo flesh grants drastically extended lifespan to the eater while binding a lingering misfortune to their descendants.
- Wail of TempestThe ningyo's cry summons violent storms and roiling seas that batter ships and unsettle coastal communities.
- Cursed BoonIf captured or displayed, a ningyo can bestow an immediate bounty or protection that inverts into tragic calamity for the captor's household over time.
Weaknesses
- DesiccationProlonged removal from seawater rapidly desiccates its skin and drains its magic, leaving it lethargic or dying.
- Salt PurificationShinto salt purification wounds its scales and disrupts its charms, forcing retreat or weakening its cries.
- Sacred SutrasChanting Buddhist sutras or binding with consecrated rope (shimenawa) suppresses its spirit and prevents manifestation of its more dangerous powers.
