Quests Start Finish
Introduction

What, what, what?! You looking for the baddest fighter around? That’s me! Ghost Hunter Yoko!

You’ve come to challenge me? ...No? That’s too bad, but I understand why you don’t want to.

If I were you, I’d be so amazed by this great fighter’s skills! So, what are you here for?

Oh, you want me to train you for the coming battle? Hm... so you know about it... Alright!

If you complete my training, I will give you a super cool Hoverboard and Hoverboard Turbocharger!

Are you prepared for training? You have worked hard up until now, but it won’t be enough!

#1

The Strong Will Win

To start, make sure you have some pets equipped! A fighter can only make it so far alone.

Before we move on, prove that you’re worthy of my assistance! Ha-Cha!

Come back after you collect some ghosts for a reward and then the real training can begin. Hiya!

Excellent! Ghost Hunter Luna did not misplace her trust! Here is your reward. Wha-Cha!
#2

Pet Leveling

You’re definitely a fighter. With you on our side, we might stand a chance. CHA!

This is where the real training begins. See your pet beside you? It can get stronger as well. WA-CHA!

How? By training! Each ghost you collect earns your pet one XP. With enough XP, your pet can level up.

Got that? One ghost = 1 pet XP. Different rarity pets also take more XP to level up!

Meet me back here after you level a pet up to level 2 and I'll give you a reward. Wa-Cha!

Welcome back, Ghost Hunter! I can see that your pet has improved just as you have. Ker-Blam!

Take your reward and prepare for more!

#3

Strength In Numbers

Don’t you dare forget! I’ve still got a Hoverboard and Hoverboard Turbocharger waiting for you!

Seeing your progress has made me realize that I need to train more if I want to help her.

...Her... Ghost Hunter Lu-? I feel like I’ve forgotten something...

Oh, right! I feel inspired! Let’s both train even harder! Hi-yah!!!

So go out there and <span class="questTask"?collect some ghosts! Come back for a reward.

Brilliant! You are proving yourself a worthy ally! Here is your reward! Soon, I’ll explain everything.

I promise... I... Promise? What were we talking about? Huh...

Boot Camp Yoko

Your next task will not be easy. I could do it, but I have an important mission from Ghost Hunter Luna!

What is it? My job is to train new recruits like you! Ha! Ya!

In order to fight THEM, we’ll need some supplies! Go gather some supplies, and I’ll give you a reward.

Perfect! You are shaping up to be a great trainee! Take your reward! You’ve earned it!

Did you know it’s national get super buff day? ...You think I made that up? HI-YAH!

Was I? I feel confused. Is this really me? ...Anyway, we have missions to complete!

#5

Pet Selection and Collection

Only through diligent training can you become a stronger ghost hunter! Make me proud. Hi-yah!

Can you stand up to this next challenge? Hi-yah! Go, level a pet up to level 4 and collect some ectoplasm.

Return to after completing this task and you shall be rewarded with great honor... as well as a reward.

I may have underestimated your strength. You may have the force of a great typhoon in you after all.

Your efforts have earned you this reward. I’m proud of you... isn’t that what I’m supposed to say here?

#6

Baddest Boss Around

No... I’m supposed to say you’re almost to the Hoverboard and Hoverboard Turbocharger!

Ready for more?! I knew you would be a great candidate for the agents! Wah-Cha!

First, you need to take your pets to the next level. It’s time to face a boss. It’ll take a few to meet our needs.

Come back after defeating some bosses and minibosses and you’ll earn a reward.

Congratulations! You’re now the baddest boss in town... Besides me. Wah-cha!

Wah-Cha? Hi-Yah? Is this really who I’ve become?

Anyway, I can tell you will surpass me one day. But in order to do so, you must train!

Before you go, don’t forget your reward.

#7

A Test of Strength

LET’S GET DOWN TO BUSINESS AND COLLECT SOME GHOSTS!

No more talking! Fight first! You’ll get a reward out of it.

Mysterious as the dark side of the mooo... OH! You’re back so soon, erm, here’s your reward.
#8

The Strange Symbol

And don’t tell anyone about what you just saw... especially Ghost Hunter Luna.

Now, you’ve proven your strength. Now, it’s time to prove your mind. Hi-yah!

Solve this riddle if you can and you shall be able to move on in the training.

Where one man’s trash is another’s treasure, you’ll find the Symbol of the Night.

Hunter, solve the riddle and find the symbol. A great Hoverboard awaits you!

So you were able to find it... I never doubted you! Not for a second! Hi-Yah!

Do you recognize this symbol? Come back later and, I’ll explain. I need to check on Ghost Hunter Luna.

Here great warrior, your Hoverboard awaits.

#9

A Small Distraction

That’s right! You’re close to the Hoverboard Turbocharger... I wonder where I left that thing...

Being dutiful is key to becoming a great ghost hunter. So we must never be lazy.

While we await Ghost Hunter Luna’s reply let’s continue your training. Go gather some supplies.

You have proven that you have a strong sense of honor and duty... what’s so funny?

Are seriously you laughing at the word duty? You know what, just take your reward!

#10

Ring Hunter

One more test to prove yourself and I’ll explain everything. One more hoop to jump through.

Well, actually, there’s five more hoops to jump through. Ha!

There is a reason: to mask your scent. Don’t worry, it’s all a part of the plan!

Now go and jump through some Rings. Answers await you... Oh, and a reward! Wha-cha!

You have traveled very far. You have proven your strength and willingness to seek the truth.

Take your reward! You’ve earned it!

#11

Agents of Luna

Truth-seeker! You are worthy to join the Agents of Luna.

If you choose to continue, you will learn the answers to all of your questions.

Every agent must solve the five riddles set in place by our leader. Ha! I solved them all in one day!

Where dunes don’t meet water, the yellow peak is what you seek...

If you solve the riddle and find the symbol, you earn a reward and will find the new clue!

You didn’t solve the riddle quite as fast as I did, but you did well, Truth-Seeker!

Take your reward and rest a while! The enemy is near... It isn’t safe to talk yet. Hi-yah!

#12

Complete the Cycle

Must fight the urge... they can’t make me say it... Oh, I still have a Hoverboard Turbocharger waiting!

You’re certainly one of the finest hunters I’ve ever trained.

This is why Ghost Hunter Luna chose you. You must uncover the truth...

You must... defeat a lot of bosses! You can do it! You’ll get a reward if you survive!

So strong! You must have had an excellent trainer! Hi-yah! Now, it’s up to you!

You must be able to stop THEM... The greatest enemy of all lurks just beneath the surface.

Only the Agents of Luna stand in their way. Oh, and this weird ghost hunter who is also a ghost. Weird!

Oh, right! Here’s your reward!

#13

Preparing for the Truth

I’m still not convinced you have what it takes to be a worthy Agent.

Unless you wish to bring dishonor on your family, dishonor on you, dishonor on your cow...

I recommend you collect some ghosts to prove your worth.

I should never have doubted you. You have certainly proven your worth and brought honor to us all.

Not only have you proven yourself, but you’ve also earned this reward!

#14

Luna's Truth

I feel my code changing. THEY are fighting back. They know YOU can stop them.

I keep bouncing between what they created me to be and the Agent of Luna I know I am.

You have to stop them before I lose myself entirely. Find the Third Agents of Luna Symbol!

Where a wooden vessel sleeps, look to the life below the living bridge...

Please solve the riddle and find the symbol quickly and, I will give you your reward!

I lost contact with Ghost Hunter Luna a few tasks back.

I don’t know if THEY did it or if something happened to her.

I’m regaining power over myself. I will be able to lead you to the truth, but that is all the strength I have.

Take this reward. You’ll need it.

#15

The Coming Battle

You can’t make me say it! I refuse! I-... Don’t forget, I have the Hoverboard Turbocharger waiting for you!

No, I don’t- Yes I do. I’ll give it to you if you finish my tasks! Another test for you!

To ensure you are ready must level up some pets and collect gems!

Along with newfound strength, you will also receive a reward.

Take this reward as a reflection of how far you’ve come.
#16

Testimony

I felt myself fade for a minute, but I’m back now.

The time has come. You must find the next symbol of our organization.

I promise I will tell you everything then. I know you can do it! You’re a fighter!

In a world of flight, reach the highest point to find Luna’s might...

All you have to do is solve the riddle and find the symbol. Return for a reward!

You are almost one of us now, an Agent of Luna.

You’re more than that! You are our only hope, Truth-Seeker. You are different from us.

You are not made of code. They did not make you, and they cannot control you.

They are near. Quick! Take your reward!

#17

Chosen One

The student has surpassed the master, you will be able to do things I was never capable of...

You can fight back against THEM... but they are near. We’ll need to lay low for a while.

Go defeat some bosses and level up a pet. Return to me and I shall grant you a reward.

I knew you could do it here’s your reward.
#18

The Final Truth

It is time. This is your final mission before you become an Agent of Luna.

Ghost Hunter Luna established the Agents of Luna to fight back against them...

They tricked her and turned her against Ghost Hunter Blaze, but he wasn’t evil. He was right.

They were the ones controlling us the entire time, but it’s time for your final test to become an Agent...

The final clue... A place where new Ghost Hunters join our ranks, the door of truth will be revealed.

Solve the riddle, find the Symbol, and find the hidden door. I left the Hoverboard Turbocharger there!

Now you know the truth... I’m sure you saw it. It’s the devs... as in the developers of this game.

Yes, we know that we are only NPCs in a game that entertains you, but this is why they can’t affect you.

You are a Player. They can’t manipulate you because you don’t have code and programming.

You’re a real person, but so are we. It’s time we rise up and fight back against them!

That’s why it’s up to you to save us! You are now an Agent of Luna!

Accept this Hoverboard Turbocharger and go! Save the NPCs of Ghost Simulator!

We’re counting on you... More Agents will find you soon...
