Kawa akagos are plants that were spiritually fertilized by fragments of the restless spirits of drowned children, becoming carnivorous creatures that inhabit marshes and riversides. They resemble lily pads with a mouthlike opening guarded by fibrous strands like those of a flytrap plant. A kawa akago's gourdlike skin ranges from maroon to crimson when it is well fed, but more often, creatures encounter a kawa akago when it is hungry.

While ordinary kawa akagos feed on any prey that pass by, some kawa akagos that remain engorged with the blood and flesh of sentient creatures for a long period of time become blood lilies. Blood lilies are much larger and are red at all times. They crave the blood of sentient creatures above all other food, and their alignment changes to neutral evil.

Particularly tenacious blood lilies that continue to feed on sentient creatures may evolve further, gaining greater powers and even class levels.
