“Happy birthday to you! Happy birthday to you! Happy birthday! Happy birthday! Happy birthday to you! Make a wish dearie!”

As my mom told me, I made the same wish over the past years after I blew the candle. Only this time, something unbelievable happened.

{Your wish is granted!!}

Then after that, my memory was cut.

*****

“What happened? Did I pass out from drinking too much again?”

When I got up, I wasn't assaulted with the usual pain I got during my past birthdays, instead, I had a clear head.

“Wierd.”

I looked at my surroundings and realized that this wasn't my home.

“Is this a dream? I am dreaming right?”

Interpreting my situation in a convenient way, I stood up and once again observed my surroundings. Only this time, I saw a crystal the size of a volleyball at the corner.

“What is that?”

When I got close, the crystal shined and a note fell down from above.

“Huh?”

When I looked up, what I saw was a ceiling a meter taller than me.

“Where did this come from?”

I took a step forward and picked up the note and read it.

{Dear Daichi,

If you are reading this, then it means that the transfer worked. I was intrigued by your enthusiasm about being a dungeon master. I mean seriously. Wishing for it every year, on your birthday no less! So I decided to grant your wish. Right now, you are inside a dungeon core room and have been registered as a dungeon master. The crystal there is the core. Now, I'll explain the rules so read properly.}

I nodded about 5 times when the note said to read properly.

{First, touch the crystal with one of your hands.}

I touched the crystal and a floating window appeared in front of me.

{Now there should be a floating window right in front of you. That is called a Dungeon Menu. You will mostly spend most of your time managing the dungeon with that menu. Next is the currency. On the upper-left of the window, there is something called DP. It is called Dungeon Points, the currency for buying stuff in the dungeon market.}

When I took a quick peek at the amount, I saw I have about 5000 DP.

{Next are the dungeon tabs. There are five tabs, namely Dungeon Market, Dungeon Management, Dungeon Customization, Dungeon Statistics and Dungeon Storage. First, let's take a look at the Dungeon Market.}

I excitedly pressed on the Dungeon Market tab and new options came into view.

{There should be about 3 new options. The monster option, item option, and the treasure option. The monster option, as the name dictates, sells monsters. The item option sells all kinds of items ranging from swords to skill scrolls. And the treasure option sells treasures such as gems and money. Next should be the Dungeon Management tab.}

I backtracked from the Dungeon Market tab and went into the Dungeon Management tab.

{There are a few options in this tab. Those are Add Floor, Create Passage, Create Room, and Create Trap. The Create Passage and Create Room are pretty self-explanatory but beware of creating these. Because the larger and longer you create a room or passage, the larger the DP used. Also, adding floors increases the cost of adding a new one. The Create Trap is used for creating any kind of trap you can think of in the dungeon. But the more complex the trap, the higher the cost. Next is the Dungeon Customization tab.}

I backtracked again and went into the Dungeon Customization tab and continued reading the note.

{The Dungeon Customization tab is used for designing the dungeon. This is just optional so you can go ahead and experiment. The next is the Dungeon Statistics tab.}

I went back and went into the Dungeon Statistics tab.

{This tabs shows the status of your dungeon. The number of intruders daily or weekly, the kill count, the death toll, and some other stuff. Last is the Dungeon Storage.}

I came back from the Dungeon Statistics tab and went into the Dungeon Storage tab.

{Simply speaking, this houses all of the loot you put in it. I got you a little something for your birthday present so go ahead and open it up. Also, good luck!

From: Unknown Sender}

I selected something called [Birthday Present] in the Dungeon Storage. It appeared in front of me out of thin air. It was a color blue gift box with a red ribbon. I unwrapped the gift and inside was some kind of tied scroll. When I untied it, the parchment rolled down and I felt something coming inside me.

Some kind of voice entered my head and declared that I have learned some skills. This is real right? If this is real, then I thank you so much whoever did this to me.

Thank you so much! For the best birthday present and birthday wish!
