Prologue

(For any readers who are new to my stories. Let me warn you that I'm not that good in making a prologue. so if the prologue is bad, Don't expect the next few chapters to be just as bad)

Y/n:... *sigh* what is taking everyone so long to get here.

I said out loud as I stared at the clock for what felt like the hundredth time today to see it's 8:03 am still.

Seeing that the time barely changed, I let out a loud sigh while boredly letting my eyes roam across the empty classroom, trying to find something that can entertain me

Y/n: ... dammit, why do I have to be in  the classroom so early compared to the students. Sure, this gives me some free time to do something quietly. But it doesn't help if I don't have anything to do!

Having nothing to do to pass the time, I just laid in my chair quietly, and began to say dream to keep my attention off of the cloak. When I was about to come up with something to distract me, I was suddenly interrupted when the door to my left opened making a small screech which echoed in the classroom

Wondering who was entering the room, I turned to see Rias gremory, and sona shitori. My first period students walking into the room with a chess board which I looked at in interest for a moment. Once they took a seat, they arranged the pieces and began to play against each other silently while I watched from a distance as there pieces made multiple small bangs as they were moved across the board

Y/n:.... *sigh* Skrew it. There's nothing better to do, so may as well ask to join.

Wanting to join in there game. I got up from my seat, then walked towards them as they were keeping there eyes on the board, once I got to them I tapped Rias on her shoulder making her take her eyes off the board then stare at me

Y/n: um excuse me you two. But can I join in your little game?

Rias: sure, mr. Y/n. I was about to get checkmated anyway knowing the previous games I had with Sona.

She said as she got up from her seat letting me take her place. Seeing that I'm taking Rias's place, Sona put her pieces back to where they were while I do the same for my pieces.

Y/n: anyway before we play. I have to say, I always expected you to play chess, Sona. But I didn't really saw Rias as a chess player at all.

Rias: well maybe you shouldn't judge people from there looks, mr. Y/n.

Y/n: yeah probably. Anyway, why don't you go first Sona.

Sona: gladly... so anyway, mr. Y/n. Why did you want to play with us?

Y/n: this classroom is as empty as a store at Black Friday, and I didn't bring anything with me to pass the time.

Sona: makes sense.

Seeing that she doesn't want to do any small talk, we silently moved our pieces all across the board while Rias spectated us.

After a few minutes of us playing against each other Sona grabbed her queen, then moved it towards the center edge of the board, then with confidence announced to me

Sona: check.

Y/n: excuse me?

Sona: your in check, y/n. All I need is to move my queen downwards, and your king is taken care of.

She said as like she said, all she needs to do is move her queen forward, and I lose. After looking at the board for a few seconds, I let out a small sigh in boredom

Y/n: well good for you, sona. But...

Without skipping a beat, I used my knight to take her king, then got up from the desk. meanwhile Rias, and Sona just stared at the board in shocked over my sudden victory

Y/n: checkmate. Anyway thanks for the quick game, you two. I really needed that to pass the time.

I told them as the bell began to ring, making multiple students come inside the classroom one at a time. Seeing that everyone is getting ready for classes, I went to my desk then waited for everyone to be seated

(Sorry, but I couldn't really think up of a good way to start this book. Mostly cause your supposed to be retired from being a phantom thief, so you shouldn't really be fighting anything now, plus I didn't want to do the stereotypical waking up scene since it's been used too much)

(Anyway don't worry. The next chapters will actually be good)
