Your Lovely Ninja (Sonic x Reader)

Reasons

This was the day. This was the day Sonic was finally going to kill that bastard Saitama. He had found the hero's address and he was heading there right now. His plan was to take Saitama by surprise and just stab him with his sword on his doorway to prove that his attacks were both quick and lethal. It was perfect, wicked, and he would never see it coming!

However, there was something else Sonic didn't see coming either....

After knocking on the alleged door of the hero, he waited patiently to strike. A few more seconds passed by before there were footsteps on the other side.

Sonic held his katana at the ready as the door slowly began to open....

And he was met with a pair of big (e/c) eyes.

The air in his lungs seemed to stop circulating as he gazed upon the gorgeous angel that stood before him. Your silky (h/c) hair, hypnotizing lips, and innocent expression mesmerized him. He was standing there for a couple of moments just taking in your beauty before he noticed that he was openly gawking at you.

He quickly cleared his throat and tried to look more composed. You on the other hand were wide eyed staring at the blade in his hands. "U-uh, w-who are you?" You asked nervously.

"Oh, uh, I-I'm Sonic. Is Saitama here by any chance?" Sonic trembled in anticipation.

"He's not here right now. Why are you looking for him?" You questioned, not taking your gaze off the katana.

He noticed your attention and drew back the sword. "I'm a friend of his, do you know when he might be home?"

"No, sorry, I'll tell him you stopped by though, bye," You stammered and made to shut the door.

"Wait!" He called out as he halted the door in its tracks with his shoe. He almost rammed himself into the crack of the door in the process. You peered out and were surprised by how close he was. "W-what do you want?"

"Can I ask, who you are...?" Sonic inquired hopefully.

".....I'm (y/n), Saitama's sister." And with that Sonic unintentionally released you and you were able to shut the door.

Your words stunned Sonic so bad that they caused him to step away when he heard them. It felt like someone shot him in the chest. You.....this glowing, angelic ember......were Saitama's sister!!? How was that even possible!?

Then again, why was he worried about this? He shouldn't care, he didn't care.....right?

Your sudden appearance merely threw him off, that was all. He never imagined that someone as attractive as you would be in his sworn enemy's apartment. Sonic was never one to fawn over women nor one to notice that they were pretty cute, he had no time for that. But you were just someone he couldn't help but admire, and he was almost positive that behind that was a beautiful personality that he wanted to meet.

Sonic shook his head. What the hell is wrong with me? Why am I feeling like this? He sighed in frustration and willed himself to forget about you.

Oh well, I guess I'll come back tomorrow when Saitama's here.

The Following Day

Sonic showed up at the doorstep around the same time as he did before. All of his plan was still the same as the previous day, the only difference today was that he was wearing a more casual outfit. For what reason, he had no idea.

Instead of threatening whoever would answer automatically, he kept his sword in its holder and knocked on the door. Seconds later, it was opened by you.
