"Crap. I used all my allowance."

I'm Naofumi Iwatani, a 20 year-old college sophomore. I'm kind of an otaku, and a pretty big one at that. I've been one ever since I got introduced into anime and manga in high school. Since then, I kinda gave up on my studies and focused more on the otaku-stuff. And my parents set their sights on my brother, giving me the freedom for me to do whatever I want. I guess you can say I'm spoiled, but whatever,that's enough about me.

"*SIGH"

I had used my monthly allowance to buy a VN of one of my favourite series. Which means, I won't be getting any allowance until next month. I do have pay checks from my jobs, but I spend most of that on merchandise and stuff. I guess this means I'm broke this month. Oh well, time to head to the library.

After some time walking , I reached the library. It isn't that far from my house. I climbed up the steps, whistling. I was soon greeted by a familiar face.

"Hello."

"Hello, Iwatani. What might bring you here?"

"Just thought I'd visit the library to read some stuff."

"Gotcha, Make sure to not knock anything over like last time."

"Dont worry about it, Last time was an accident."

"Whatever you say."

I quickly zipped over to the novel section. Or specifically the Light Novel section.

"Hmmm, what book should I read?"

I started looking around, trying to find something worth reading. I have read most of the books here, since I'm rather of a regular customer around here. One book which I haven't read or seen yet appeared at the top of the shelf.

"Huh? I haven't seen a book like this before."

The book was titled "The Records Of The Four Holy Weapons". I reached up to take it, but it fell on the floor, upsetting a couple of other books on the shelf. The books fell with a big THUD on the floor. Soon, the librarian came around.

"Iwatani?! What in god's name is going on here?!"

"U-Uhhh, I can explain!"

"Please tell me you haven't spilled the books on the floor again."

"I-It was an accident, okay? I'll clean this up right away!"

"Fine. Make sure it doesn't happen again. I don't want disturbances in the library."

"Ehehehe, sorry."

He went back to his work. I quickly cleaned up the books and got a look at the weird one out of them.

"Records Of The Four Holy Weapons, huh? seems like one of those corny isekai novels which everyone makes. Too bad, seems like I got my hopes up."

I, rather disappointedly, put the book back on the shelf. I wasn't too keen on the isekai series, since I lost interest in it after reading too many of them. I looked over any other books to see if I could find any but I couldn't. I decided to ask the librarian.

"Hey, are there any new light novels yet?"

"Not yet, Unfortunately. The new delivery comes tomorrow, I think."

Oh well, seems like I have to come back tomorrow. Well that was a waste of time, I think I'll just play my VN's until I get something else to read.

I walked down the hallways and almost exited the library before I spotted something out of the corner of my eyes. It was one of those oval-shaped mirrors, which you could look into to see yourself. "I don't remember seeing that last time." I thought. I walked over to it and took a look.

"..."

"What the hell?"

What I saw baffled me. I did see my own reflection, but I was wearing a traditional Japanese garb, not unlike what you would find in a movie in the Edo period. And instead of showing me in a library, it showed me standing in the middle of a road. What was most surprising though, was that the passersby behind my 'reflection' were not humans, but rather dwarves and elves, and some sort of translucent ghost-like people?

I curiously decided to touch it. But, I tripped on my foot and fell forward when my hand completely phased through it. I quickly regained my balance, but my hand was stuck in the mirror, moreover, I couldn't get it out. Then, it started dragging me in. I tried pulling my hands free, but it didn't work. Before I knew, my whole body was being dragged into the mirror. I tried pulling away from it using my feet, but my feet slipped and I fell right in. The last thing I could've sworn I saw was the book which I picked up from before flying towards me?

"WHAAAA-"

I don't know how long I fell, but when I opened my eyes, I found a robed man and some people, Also wearing robes, behind him standing in front of me and looking directly at me.

"Sir, the summoning was a success!"

"Wait, what the fu-"

"So, Kufilka, you're saying that they decided to summon a vassal hero instead of selecting one?"

"Yes, Your Majesty, or so I have heard."

"Hmm… It'll be interesting to see how this plays out…"
