Western Crossover: I’m Not a Slime!

Ruby transmigrated. Suddenly, she became a soft, squishy alien symbiote who could only move around by attaching herself to someone else. She was a pure support type, incapable of functioning without a Host. The only way to become a normal human again was to achieve perfect compatibility with the Hosts chosen by the System. And so Ruby began her humble journey as an alien who clung to powerful people and begged to be their symbiote. Ruby: Please, please let me bond with you QAQ I can make you stronger, I swear! At first: The Hosts: Eek! Where did that slime come from? Get away from me! Later: The Hosts: Why? I was the one who got bonded first. How did things end up like this... P.S. The female lead can turn into a human later on. Her character design is on the cover. She's adored by everyone, with no romantic pairing. Warning: 1. I write for fun, and making myself happy comes first. The plot may have severe cases of catering to my personal tastes. I've had this condition for years and it still hasn't been cured (hey!). 2. My thought process is a little unusual, so if any plot point or description offends you, I'm truly sorry. Run away! 3. All the following symptoms are present: poor writing, OOC, intermittent character derailment, and chronic logic death. 4. If you enjoy this story, thank you so, so much. I'm truly honored. The blurb ends here. Up next, some stories to add to your reading list. [Western Crossover] I've Got This Earth Covered Hawthorne Dylan transmigrated into an Outer God. Known as the pen that sculpts civilization, the eye that observes the universe, and the watcher who sees the trajectories of countless fates, his greatest joy was writing down knowledge with a quill, recording civilizations, and expanding his collection. However, Hawthorne had only just transmigrated and wasn't familiar with the job yet. Half-asleep, he unconsciously guided several humans into his dreams. They glimpsed forbidden knowledge, awakened the sealed Old Ones on Earth, and now it looked as if the planet was about to blow up. Hawthorne: ...What a complete mess. With no other choice, he put on a secret identity and descended to Earth, hoping to help humanity avoid this disaster. “Those stupid Old Ones can all get lost! I've got this Earth covered!” The first day after descending, he was arrested for “acting like a lunatic, scrawling all over the place, and preaching nonsense.” The Outer God Hawthorne, forced to wear handcuffs: ...Damn. As he worked to save Earth, he gradually discovered that the world had quite a few superhumans with wills strong enough to withstand his gaze. They were perfect vessels for an Outer God's will to descend into, and could be sacrificed without pain! And so... “Mr. Wayne, Mr. Rogers, Mr. Stark, and all the other gentlemen, could I have a moment of your time? I want to tell you about our Heavenly Father and Savior, Hawthorne Dylan. Oh, sorry, Mr. Kent, you can sit this one out. Your inspiration and willpower are both so painfully inadequate. You're the weakest one here. If you don't want to go insane and be sent to Arkham, keep your distance. Thank you.” The powerless Kryptonian: ... Reader's guide: 1. The male lead is a genuine Outer God. He's kindhearted, not cold or sinister at all, but his true form looks very Lovecraftian and intense. The settings for various Outer Gods, Great Old Ones, and Old Ones have been heavily modified, so this isn't a traditional Cthulhu Mythos fanfic. Please don't take it too seriously, and lore enthusiasts, please go easy on me. You don't need to know the Cthulhu Mythos to enjoy it. 2. His true form is too powerful, and ordinary humans die from looking at him, so for everyone's safety, the protagonist can only act through secret identities, and he has plenty of them. He'll never be unmasked. 3. Being cool is second nature to me. Proceed at your own risk. The Lovecraftian elements are intense and niche, so readers with low tolerance for psychological horror should take care. Theme: Companionship and growth
