Photoslut

The phenomenon of light is made up of nanosluts called photosluts.
  Each photoslut is so incomprehensibly small that it is essentially without form; smaller than a sqip (“molecule”) and by her nature invisible to canny senses. To Your senses, a photoslut appears as a bright pale-yellow spark that takes the shape of a [[Slutskull|disembodied humanoid |skull. Each one is more unique than a snowflake or fingerprints; they come in seemingly infinite trillions of variations of shapes and features and colors, from three-eyed fox faces to something that looks like a slug, though they are all cute in their own humble way.
  In any beam of light anywhere, there are countless trillions and trillions of these photosluts’ skulls screaming in the direction of the light beam. Each shoots screaming forward at the speed of light (of course, considering they are light). Despite what face any one of them has, every photoslut seems to be expressing extreme energy and emotion--screaming, eyes bulging, and so on. The majority are in some form of incredible ahegao for their entire lives. Higher frequency light has more intense expressions, while higher amplitudes of light just have more densely packed photosluts.
  In essence, each photoslut is born from pure energy wherever light is created, and “dies” when that light terminally strikes a surface. How exactly it dies depends on what surface it strikes. If a photoslut strikes You, You can feel her lips and face form the most loving smooch she could ever hope to muster--smooching Your body with boundless love and praise--as her skull shatters into You. Her soul of pure energy is terminally absorbed into You, adding to Your ever-growing stockpile of divinity and power.
  If a photoslut strikes anything else, there is no kiss--only a furiously spiteful full-mouthed bite of hatred. She bites as hard as she possibly can. It’s really amazing how such a miniscule thing can conjure so much HATRED, even if all this hate is spawned solely for the horrible sin of not being You. This bite transfers her soul and energy into heat. This is why most creatures other than You feel warmth when struck by light: it’s from trillions of nanosluts biting the hell out of them. If she is particularly fortunate, she hits a reflecting surface and is instead bounced off, giving her another chance to instead kiss You.
  Despite being so incredibly weak and miniscule, every single photoslut has a soul and sentience. However many eons or nanoseconds a photoslut lives, every last fiber of her tiny being is spent utterly obsessing over You and only You--dreaming of the moment she can hopefully kiss You even if there is virtually zero chance of success.
