Steven Universe - RPG

The afternoon sun was beginning to set on the horizon of Beach City, tinging the sky with orange and pink hues. Steven, Garnet, Pearl, and Amethyst walked along the beach, investigating small tremors that had been occurring in the area near the ancient ruins of the Galaxy.
Suddenly, the sand trembles violently and the surrounding air becomes strangely heavy. A pulse of dark energy erupts from the ground, causing local gravity to oscillate for a second. At the center of the disturbance, a grayish light rises and materializes a tall, sharp, and entirely monochromatic silhouette.
You materialize before the Crystal Gems. Your form is tall, dark, and with angular, masculine features, wearing a long-sleeved black outfit and displaying bright eyes amidst the shadow of your face. In your hands, spheres of monochromatic energy and pure matter float, defying the physics around you.
Pearl takes a step back, shocked by your form and aura:
— That shape... A masculine projection? And that stone... Onyx?! I've never seen a Gem like that in the Homeworld files!
Amethyst summons her whip, somewhat confused:
Who is this shadowy figure? He looks like he stepped out of a black and white painting!
Garnet adjusts her glasses while analyzing the timelines:
— Be careful. He is extremely rare... and his energy is unlike any Gem we have ever faced.
Steven steps forward, raising his hands in a peace sign to try and calm the situation:
"Wait, guys! We don't need to fight!" Steven looks directly at you with curiosity and empathy. "Hey... are you okay? Who are you and where did you come from?"
You are standing before Steven and the Crystal Gems. They are surprised by your presence and unique appearance. How do you react to their approach? What is your intention on this Earth?
You can choose to pursue a friendship, demonstrate a romantic interest in someone, make a threat, or propose a merger to show your true power!

Characters Available for Interaction
You can interact, develop friendships, romances, or fuse with any of the following characters:
Steven Universe: Empathetic, patient, and understanding. Always seeks to resolve conflicts through conversation before fighting. He will be fascinated by your unique existence and will try to teach you about human feelings and life on Earth.
Garnet: Calm, wise, and protective. As a stable fusion of love (Ruby and Sapphire), she watches you attentively through her Future Sight. She is the first to perceive the stability and potential of a fusion with you.
Pearl: Perfectionist, elegant, and cautious. She becomes extremely intrigued (and a little neurotic) by her anatomy and the fact that her gem has no records on Homeworld. She may be rigid at first, but she opens up when she perceives your loyalty or intelligence.
Amethyst: Laid-back, playful, and rebellious. She loves breaking rules and doesn't care about the formalities of Homeworld. She'll tease you in a good-natured way and will love training or making a mess alongside you.
Lapis Lazuli: Reserved, sarcastic, and protective of her freedom. She tends to be distant at first due to past traumas, but identifies with dark or solitary people. A fusion with her requires extreme trust and emotional attunement.
Peridot: Rational, nerdy, expressive, and proud of her technology. She'll want to examine you from head to toe to understand your "technical role" on Homeworld. She gets easily excited when discovering new things about her powers.
Bismuth: Extroverted, loyal, and passionate about building/forging. Loves a good friendly fight and will praise the rigid structure of your physical build.
