It's a Nephilitic (not demonic, big difference) entity that will manifest on your wall as a set of mismatched loving eyes (the angelic part), a bottomless mouth connected to the pits of hell that will devour anything (demonic part) and a human brain of very modest capacity (leftover human part.)
You can only summon it if you are an incelibate, virgin, degenerate otaku with his mind in the gutters and if you perform an elaborate ritual involving 777 supas in a specific color pattern.
At which point, what will you do with the entity is up to you. You can love it, you can care for it, you can smooch it until you pass away, you can feed it any sort of bodily fluid and it will always love you back, although sometimes in a misguided way.
