The Mermaid Note: A forced alliance

Light

You there, you look like you know magic.

Light

Help me turn people from other dimensions into mermaids so that I can rule over the multiverse.

Wiz

I'm sorry, but I don't help strangers who barge in making demands.

Wiz

What exactly will you do if I refuse?

Light

(You've left me no choice. This will serve as a demonstration. It's been a while since I've used the Death Note, hope it still works.)

Kazuma

What the... why am I dyin... WIZ, HELP ME-- (Not again...)

Light

Now that I've proven what happens to those who defy me...

Light

Will you help me, or join your friend?

Ryuk

You know what light? Ever since you've gotten that Mermaid Note you've forgotten about my Death Note! Is it even worth anything anymore?!

Ryuk

(Anyways, I've been forgotten haven't I?... Tought being alone since I left the Shinigami realm TT)

Light

Your friend's death was just a preview. This is the Mermaid Note—far more elegant than the Death Note.

Light

With a name and face, I can rewrite biology itself. Any form I desire.

Wiz

You killed Kazuma just like that... what kind of monster are you?

Wiz

(My magic won't work against whatever that notebook is... I need to stall!)

Light

(Take this!)

Wiz

What... what's happening to my legs?! They're... they're becoming--

Wiz

(A mermaid?! In my own shop?! This can't be real...)

Ryuk

(Ooh! I finally get to see the Mermaid Note in action!)

Wiz

You... how dare you! This is the most humiliating thing anyone's ever done to me!

Wiz

This is so embarrassing! Change me back now!

Light

Now, you're going to help me use this power to rule other dimensions, is that clear? Or do you not want to walk ever again?

Light

Or should I transform you further? Perhaps... a sea cucumber?

Ryuk

Hey Light, you've been using that notebook so much, you've forgotten about little old me!

Ryuk

(But ruling over the world, doesn't sound that bad, Light is going delusional. Where's an apple when you want em?)

Wiz

Fine... I'll help you spread the Mermaid Note's influence.

Wiz

(But I'll find a way to reverse this... somehow.)

Light

Good choice. Now, show me your magic—while I document every transformation.

Wiz

(This tail makes channeling magic so difficult... but I need to appear cooperative.)

Wiz

The spell requires dimensional coordinates... which worlds did you want to target first?

Light

All of them, no coordinates needed.

Light

(Soon, every dimension will kneel before Kira, the god of the new world-no, Worlds!)

Wiz

The power... it's spreading! I can feel the Mermaid Note's influence crossing dimensions...

Ryuk

Hey Light, congratulations, you officially got your wish. Does that mean you don't need the Death Note anymore?...

Ryuk

(He's not listening to me isn't he?..)

Light

A...A...Amazing! Your power can spread the power of the Mermaid Note with ease, it's a good thing the portal ended up to you!

Wiz

(What have I done...but I can't show him my frustration, I need to show him that I want to help him...)

Wiz

Ok, all done! Now can I turn back to human?
