"Angels" is what they were originally known as to many different species. Appearing as beasts, humans, or otherwise to blend in with native species, they came from nothing, and with the ability to grant boons and wishes. They are but another species from another place, the material of their home planet, an unusual star, capable of performing miraculous acts, whilst consuming the material.
But another entity roamed the stars as well - made up of dark matter it had a voracious hunger for the star material, and would attempt to hunt down these angels, these dimensional travelers, for the material that they carried with them. If caught, the traveler would become infected - would become a Komaruhoyo. Troubled souls, grounded wherever they had been infected, and often cursed with other changes, whether mentally or physically, they would often become a nuisance for the world they were now permanently stranded on.
Ultimately a Komaruhoyo is defined by how their extended contact with the star material has affected them. Afflicted area's should be the darkest color on your Komaruhoyo (not including clothes or line art). Affliction generally manifests in a few particular places:
After being afflicted, the star material the Komaruhoyo was holding is also impacted and becomes a small solid chunk with a diamond like center. This new material is bonded to the Komaruhoyo, and if separated the Koma will continually lose energy until they are no longer able to move, and eventually pass away. As such Koma will keep this source of life close by and often attached to a part of their outfit like a bow, tie, or similar.
The life source shape must be round with a star (✦) shape in the center, resembling the home that Koma's can no longer return to.
The primary defining feature of the dimensional travelers Komaruhoyo originate from.
Inside the ears are "all-seeing" eyes that allow them to see and hear at a greater
distance, and often see "into" the mind of those around them. If other beings make
direct eye contact with these eyes however, they can do great harm, so many Komaruhoyo
leave their ears zipped up to avoid this repercussion.
The ears themselves can be any type of real world animal ears as long as the zipper and/or eyes are visible.
A Komaruhoyo's tail is typically afflicted, and matches the same dark color used on the life source. Afflicted tails can be any shape but are largely un-textured. Some afflicted tails may even have their own limited eyes and mouth.
A Komaruhoyo's wings are also typically afflicted, and should match the same dark color as all other afflicted areas. Afflicted wings can be any shape, but are also un-textured.
A Koma may change the size of their wings at their own whim, as well as whether they're wings are floating behind their back or attached.
