I'll Crush You with One Strike, Mr.Spider.

Hello, all. How's it going? Today, let me talk about something scary that happened to me the other day.
When I was chilling at home, I caught something black at the edge of my sight. I was like ” Don't tell me...”, but that was definitely it. Yes, a spider. I gasped and froze. Even though I'm scared of spiders, I can manage to stand and to handle small ones. However, the one that appeared on that day was extremely big! It even looked like a kind of spiders that didn't live in Japan. I freaked out and almost screamed. Ugr...it still makes feel even still made me disgusting although it was some days ago before. At least, it was good that the spider stayed still on the wall. If it was crawling up my leg, I absolutely would have gone crazy. What if it escapes once I stimulate it?! I'd run away out of my room and wouldn't be able to come back. So I made up my mind to kill it no matter what.

That being said, I was really scared since I had never seen such a big spider. I had no idea how it would move. Walk? Or jump? Either way, I had to get it with one strike for sure. It'd have been messed up more if I missed and let it go.
I picked up a rolled-up magazine. Okay, I've got a weapon. Here I go. The closer I got to the spider, the more nervous I became. At the next moment, I hit it into next week, and the spider quietly dropped onto the floor. Victory! Yay.
I felt sorry for it, but I was relieved that it that was over.
How in the world did it enter my room? I still have no clue...

Nice victory and great writing style! You write great stories.
