Amabie - Japanese spirit: "(アマビエ)". She (or He?) is a yōkai - a spirit guardian who when looked at as an image, is said to offer protection from plagues and pestilance. She is a beaked mer-maid, with a scale-covered body, and a bird-like beak and three fin-tipped legs, who appeared to a fellow in the 1840's, who was investigating a strange green-glowing light at night, in the sea, near Kumamoto region of late-Edo period Japan. This a public-domain image of a wood-block protective print from that time period.
She was supposed to have spoken, and specifically forecast six years of bumper harvests, but also a nasty plague. However, she indicated that if images of here were seen by many people, her very appearance in glyphic (manga?) form, would offer spirit protection from the coming plague.
Her image is being widely shared, and has even been painted on the underside of Japanese passenger aircraft.
In Canada, where vaccines are not available, looking at her image for magical protection makes as much sense as trusting our current government to do anything constructive, so we figured it can't hurt! :)
