The shadow assassin (steven universe reader-insert)

Chapter 20.

Garnet : (growls*) This form isn't sustainable, Amethyst

Amethyst: (blushes*) But... (looks down and shots at Garnet*) You're the one who said I needed to be stronger!

Hissing is heard again and the trio look around. Amethyst pounds her fist on the ground.

Amethyst: Okay, if it's my monster then I'll deal with it!

Amethyst runs toward a crystal pillar and punches it out of her way, shattering it. Steven and Garnet shield themselves from the debris and follow after her.

Steven: Amethyst!

Steven and Garnet lose sight of Amethyst. Garnet then grabs Steven, leaps off in the direction of the hissing, and sets him down.

Garnet: Stay behind me! (runs through another tunnel and looks around*)Amethyst!

More debris are flung towards Garnet, who quickly shield herself with her gauntlets. Amethyst can then be seen fighting the Slinker hand-to-hand.

Steven: (gasps*)Amethyst!

Amethyst wrestles with the Slinker, laughing and slamming it against a crystal pillar with her bulk arm. The Slinker tries to retaliate by wrapping its tentacles around Amethyst.

Garnet: Let it go!

Amethyst: No! You wanted me to be stronger, I'm doing it! I'm being what you want!

Garnet: I don't want this!

Amethyst's bulk arm is unable to be sustained and it deforms. Amethyst struggles to push back the Slinker.

Amethyst: Well, what do you want? Just tell me and I'll do that!

Garnet: I can't tell you, Amethyst! You have to figure this out for yourself! (Amethyst grunts in pain*)

Steven: She can't! She doesn't want to think about herself!

Amethyst: WHAT?

The Slinker eats the distracted Amethyst and poofs her. Garnet leaps in and punches the Slinker,the slinkler however, amethyst's gem drops and it blocks it's attack and land a huge hit on garnet, causing her to back down a little. The slinkler then jumps  at them. Garnet jumps back and Steven forms a bubble to protect his self, he now deactivated his bubble. And the slinker was now charging on steven, causing him to cover his self as a preparation for an incoming hit. The slinker now use of it's tentacles to try and hit steven

Garnet: Steven, NO!!

The tentacle was now going to hit steven and he closes his eyes, until a slash was heard. Garnet and Steven realize that it was you defending steven from that beast with your double sided sword. The slinker now gets angry and uses his tentacles to grab and hold you. You swiftly dodge some of it. You landed at a tentacle and slashes all of the tentacle hitting you including the one that you landed on. The Slinker now screams in agony as most of it's tentacles is cut down. You now jumps backwards, landing perfectly. The monster growls at you and you charge at it with all your might. A big slash was done, you and the monster are now toe to toe. The monster now slowly and slowly overpowers you. But you remember what that monster did to amethyst and you've close your eyes. The monster is now preparing it's final blow, until your eyes open.

Your eyes are now finally just like your diamond eyes when you've fight iron and jasper. You now slowly and slowly gets stronger. Your double sided sword slowly turns into a shadow sword. You now scream in anger as you fastly slash your sword, your sword instantly grows a hundred time thatn your old one. The Slinker was sent off flying as you fainted and garnet catches you.

Garnet: (holding you*) Are you okay y/n?

You: Yeah, I'm fine...

Steven now walks to you two having amethyst's gem on his hands. He sighs as he holds it against his chest.

Garnet: Good catch.

At the Beach House*

You, Steven, and Garnet are back in the house. You are lying on the couch, holding some blanket and a cup of coffee to warm you. Steven is lying on the couch too, holding and staring at Amethyst' gem, while Garnet is talking with Pearl.

Pearl: I knew that thing was real! When Amethyst gets back we have to go find it! Except, we will not need y/n for this. Not that's because we don't want him, it's just for his safety.(walks over to Steven*) How long has it been?

Steven: 4 hours...

Pearl: 4 hours?! She's never taken so long! What do you think she's doing in there?

Garnet: (arms crossed*) I'm not sure, I was too hard on her.

You: Well...(sips some coffee*) No matter what form she will take next, we need to support her.

Steven sighs, when Amethyst's gem starts glowing again.

Steven: Oh, oh, she's back! (Amethyst's gem floats off of Steven's hand and starts taking form*) All right, let's follow your suggestion y/n, everyone be supportive.

Amethyst's form continues to cycle until it sticks, and Amethyst returns with a new outfit. She lands on the table, yawns and stretches.

Amethyst: What?

Steven: (slightly disappointed*) Aw, you barely changed.

Pearl: Steven!

Garnet walks over to Amethyst, and they look at each other briefly.

Garnet: It's perfect.

Amethyst: Eh, whatevs. It's just what feels right.

Garnet: That's why it's perfect.

You: (stands up*) Indeed, i prefer your original form...

Pearl: It is a marked improvement! You finally fixed that shoulder strap that's always bugged me!

Steven: Welcome back! (hugs Amethyst*)

Pearl: Well done, Amethyst! (hugs Amethyst too*)

Amethyst: (blushes*) Knock it off! Huegh! (Garnet hugs her too.*)We gotta go find the Slinker!

Steven: No, it's hug time.

Amethyst: Ugh, this is so dumb.

You are just smiling at them, because you are really happy. Steven notices you lonely and whispers something to the crystal gems. The four of them scotches to you slowly.

You: No, no! Guys, I don't need it.

The four of them jumps at you. They now hug you and you hugged them back.

You: Guys, aren't you worried about me? You know, having these immense power and all...

Steven: We are worried about you y/n, but it's hug time for now.

The five of you laugh at each other. Yoh now truely feel that you are apart of their body and they accepted you. You now turned to amethyst.

You: And amethyst, please don't be worried about your form. We accept you just the way you are.

The star iris then closes on Amethyst, who smiles cutely and sighs in satisfaction.
