I tried okay...I'm not that good but I wanna give it a try...sorry for the cringe and just turn away from this book so you wouldn't feel bad...

Plus my friend dared me to do this...

Here goes...

Shaira:
Let it rap!
Two hot boys going to fill this gap!
The Stamina king Free!
And the Ice lord Lui!

And begin!

Free:
Dragon blader, are you really?
I complete that role better,
Hand to hand combat in this rally,
I can break your bones faster than a boulder,

I'm the golden boy in this battle,
Crack my knuckes, let's get this settled,
Bringing out my Fafnir,
Here we go!
Shaking like a little baby, out of fear!
What a short foe!?

Lui:
Heh, you verse is nothing,
Compare to my destroyer,
Mine can flew higher,
What about this yellow groundling?

You're a Shu Kurenai wanna-be,
Getting this much popularity,
Triggered? I'm sorry,
Not really,
Because your just a failed copy!

Free:
Tch, throw a bucket of water on that instead,
See if you still have hair afterwards on that bold head,
Having intearest in Lane, ring any bell?
Say hello to Lucifer when you meet him in hell,

Lookin for Ben Azuki?
My thoughts are going crazy,
Pink hair? Spiky and the attitude,
Oh wow, genetics comperable dude!

Lui:
Compare me to Lane?
Yeah as if you're any better,
Fumiya is into the same fame,
And wait-is Joshua the father~? (Eww)

Hah! Take that son of yours outta here,
Just like his own mother, a mimic failure,
I'm Lui Shirosagi, the Ice Dragon Blader
Free-ze you in place while I watch with a cold sneer
Now go to heaven where your daddy is a deer.

Free:
Uh...I don't even have a father..
Come to think of it, not even a mother,

Lui:
Really? Me neither...
Now you said, other than the protagonist, no one else have either...

Free:
Guess this explains our manners...

Lui:
Wanna play this backward?

Free:
No way, while I got you mopped on the floor,
Beat you on your own game before I leave through that door,

Lui:
I've beaten you before,
This should be an easy victory forked,

Free:
Pft, I won't even need to glance...

Lui:
You're not taking the trophy from me, I'll beat you before you get a chance.

Free:
You really think so?

Lui:
I know so...

Free:
Alright, let's dance...
