Kas opened the card he was given on the rooftop.

"Brother, I am currently on my way to your apartment. Based on my flying speed, I should arrive sometime tomorrow. Mind if I come in and fight you for your lesson to the students? Don't worry about the kids, I have Maya, Lira, and Jason with their dad while I'm here."

Kas smiled, and went to sleep in his room.

The next day passed, and Terry wrote two words on his chalkboard: teen angst. This was the next weekly lesson, and people were pleased with this.

"The assignment is to sing a song about either teen angst or a song with a motivational theme.

A student volunteered to start with the assignment, and Terry gave her the floor.

The snow glows white on the mountain tonight
Not a footprint to be seen
A kingdom of isolation
And it looks like I'm the queen
The wind is howling like this swirling storm inside
Couldn't keep it in, heaven knows I've tried

Don't let them in, don't let them see
Be the good girl you always have to be
Conceal, don't feel, don't let them know
Well, now they know

Let it go, let it go
Can't hold it back anymore
Let it go, let it go
Turn away and slam the door
I don't care what they're going to say
Let the storm rage on
The cold never bothered me anyway

It's funny how some distance makes everything seem small
And the fears that once controlled me can't get to me at all
It's time to see what I can do
To test the limits and break through
No right, no wrong, no rules for me
I'm free

Let it go, let it go
I am one with the wind and sky
Let it go, let it go
You'll never see me cry
Here I stand and here I stay
Let the storm rage on

My power flurries through the air into the ground
My soul is spiraling in frozen fractals all around
And one thought crystallizes like an icy blast
I'm never going back, the past is in the past

Let it go, let it go
And I'll rise like the break of dawn
Let it go, let it go
That perfect girl is gone
Here I stand in the light of day
Let the storm rage on
The cold never bothered me anyway

...

Yet another student came up to the center of the choir room with their song.

The clock stopped ticking forever ago
How long have I been up I don't know
I can't get a grip but I can't let go
There wasn't anything to hold on to though

Why can't I see?
Why can't I see?
All the colors That you see

Please, can I be
Please, can I be
Colorful and free

Send me a sign, some god on high, show me the words I need to know
So say I'm fine and clear my mind
'Cause why not? I DON'T KNOW

I'M BLACK
THEN I'M WHITE
NO SOMETHING ISN'T RIGHT
MY ENEMY'S INVISIBLE
I DON'T KNOW HOW TO FIGHT

THE TREMBLING FEAR
IS MORE THAN I CAN TAKE
WHEN I'M UP AGAINST
THE ECHO IN THE MIRROR

ECHO

What do I spy with fully open eyes?
All that I spy are idiots and lies!
What do I spy with fully open eyes?
All that I spy are idiots and lies!

Aah, can never get enough of the right stuff
Needles oversized to pulverize this heart beating out my chest

Send me a sign, some god on high
Show me the words I need to know
But where's my mind gone?
This is all wrong!
Why not
I don't know

Facing a new day with a new pain, rocking up and down the night
WHEN I'M UP AGAINST
THE ECHO IN THE MIRROR

THE TREMBLING FEAR IS MORE THAN I CAN TAKE
WHEN I'M UP AGAINST
THE ECHO IN THE MIRROR

In the fallen night and days, a corpse of mine will explain
As long as you can smile,
I'm not the toy you will love

...

Terry dismissed the class, and the students arrived shortly to have lunch.

Kas locked the training hall, and started to practice his fighting on several dummies. He heard some knocking on the door, and paused for a second before opening the door. To his surprise, nobody was there. He closed the door, and heard two people in the background, recognizing the voices belonging to Khaston and Cleo.

Khaston Cleo

I know that I'm running out of time
I want it all, mmm, mmm
And I'm wishing they'd
stop tryna turn me off
I want it on, mmm, mmm

And I'm walking on a
wire, trying to go higher
Feels like I'm surrounded
by clowns and liars
Even when I give it all away
I want it all, mmm, mmm

We came here to run it, run it, run it
We came here to run it, run it, run it

Just like fire, burning up the way
If I can light the world
up for just one day
Watch this madness, colorful charade
No one can be just like me any way
Just like magic, I'll be flying free
I'mma disappear when they come for me
I kick that ceiling, what you gonna say?
No one can be just like me any way

Just like fire

B-b-be carful making wishes in the
dark, dark
Can't be sure when they're hit their,
Mark, mark
And besides in the mean mean time I'm
Just dreaming of tearing you apart
I'm in the d-details with the
devil
So now the world can never get me on my
level
I just gotta get you out the cage
I'm a young lover's rage
Gonna need a spark to ignite
My songs know what you did in the dark
(we came here to run it, run it, run it)
We came here to run it, run it, run it

Just like fire, burning up the way
If I can light the world
up for just one day
Watch this madness, colorful charade
No one can be just like me any way
Just like fire
(Both So light em up, up, up
Light em up, up, up
Light em up, up, up
I'm on FIRE
So light em up, up, up
Light em up, up, up
Light em up, up, up
I'm on FIRE
Oh oh whoa oh whoa oh whoa
We came here to run it, run it, run it

So look I came here to run it
Just 'cause nobody's done it
Y'all don't think I can run it
But look, I've been here, I've done it
Impossible? Please
Watch I do it with ease
You just gotta believe
Come on, come on with me

Oh, what's a girl to do?
Hey, what's a girl to do?
Oh, what's a girl to do?
Oh, what's a girl to do?

Just like fire, burning up the way
If I can light the world
up for just one day
Watch this madness, colorful charade
No one can be just like me any way
Just like magic, I'll be flying free
I'mma disappear when they come for me
I kick that ceiling, what you gonna say?
No one can be just like me any way
Just like fire, fire

Run it, run it, run it
Just like fire
Run it, run it, run it

...

Kas decided to wrap it up, and unlocked the training hall. He took his keyboard, and put the whip in an empty slot. He walked to the choir room, where he saw Yun singing with Terry on backup.

Yun (Terry)

Blackbird singing in the dead of night
Take these broken wings, and learn to fly
All your life, you were only waiting for this moment to arise

Blackbird singing in the dead of night
Take these sunken eyes, and learn to see
All your life, you were only waiting for this moment to be free

Blackbird, fly (Fly)
Blackbird, fly (Fly)
Into the light (Fly) of the dark black night (Blackbird, fly)

(Uh, uh, uh, uh, uh..., uh, uh, uh!)
(Tarara-rara-rara-raararararaaa)

Blackbird, fly (Fly)
Blackbird, fly (Fly)
Into the light (Fly) of the dark black night (Blackbird, fly)

(Uh, uh, uh, uh...)

Blackbird singing in the dead of night
Take these sunken eyes, and learn to see
All your life, you were only waiting for this moment to arise
You were only waiting for this moment to arise
You were only waiting for this moment to arise

...

Yun left the choir room, thinking that Kas and Terry were going to have a conversation.

Terry saw Kas walk in, and didn't mind anything. Wayne entered shortly after, wondering how that exit from the concert was possible.

"I was at that man's concert when you and him left in light and feathers. Are you hiding something, Kas?"

Kas and Terry looked at each other for a second, then hid inside of a closet with Wayne so they could explain everything.

After explaining the situation to Wayne, the three teachers went back to their respective classrooms, and began with their next class.

Meanwhile in Emma's class, Khaston and Yun were having a dance off while Blue Chandler was singing.

Even if I close my eyes
The morning will come again
The nights that I've come to dislike
They cannot be counted

When I gaze up at the sky
My vision is hazy
When I turn and look back
I can no longer return to the past

Even if it's a lie
I would like for you to stay
Always, it doesn't matter when
You are in my memory

Like the tears which overflow
If I cannot stop this feeling
Until I wither and die, I will scream
Until it reaches you
Until I can always be heard

Tangled in strings
If I have been tethered to life
I'd be able to laugh and say
That I would never unravel and come apart

Even if the wind blows
Nothing will ever change
By the time I finally realised it
I didn't have the wings to fly

If you are going to vanish again
Together with the seasons that have been dyed
Time, please move forward no longer
Stop for all eternity

Terrified of a future I cannot see
The hand that was linked, I let go of it
Before the dawn breaks, let's go on a journey, right now

To you I couldn't say
Even goodbye
I would definitely remain frozen in place all by myself
And again the morning will come

Like the tears that overflow
One day, they will fade away
Until I wither and die, I will scream
Until it reaches your heart
Until it reaches you always
Until I can always be heard

...

"Don't forget, the classes battle each other soon! Ask Terry about what your peers are doing!"

The last class of the day started, and Kas was teaching the students fighting techniques.

Khaston looked out the window, and saw a woman using magic to fly toward the window through the courtyard. He saw a visitor's pass, so he knew that someone wasn't casually about to attack.

The window shattered, and the woman slid into the room, picking a fight with Kas without reason. She summoned her weapon: a staff, and charged at the teacher, who used his keyboard as a shield. Kas then took his whip out, and parried the staff. He then stuck his hand out, and launched a blast of ice, which was then shielded by the woman spinning her staff. They charged at each other, both using a powerful enhancement spell on themselves. The two both struck each other with their weapons, and the students were trying to find out who won the fight. The results came when the two got up, the woman put her staff away as Kas kneeled and grabbed his gut. The woman helped him up, and used healing magic. After that was done, she introduced herself.

"I'm Kyra, his older sister. I come here from A-"

"A-An area in the Agni Empire! (Kyra, you need to be careful!)" Kas interrupted, fearing Kyra was going to slip up.

Kyra places her staff on the wall, and watches Kas teach martial arts to the students. After the lesson, students began to leave the training hall when Khaston asked Kas a question about his interruption

"Why were you covering up for your sister when she said where you two were from?"

Kyra giggled, which led Kas to say that she likes to joke around with some things, especially the personal parts.

Khaston left the room, leading the siblings to do a duet once he left.

Kas Kyra

There's only two types
of people in the world
The ones that entertain,
and the ones that observe
Well baby I'm a put-on-a-show kinda girl
Don't like the backseat, gotta be first

I'm like the ringleader
I call the shots
I'm like a firecracker
I make it hot
When I put on a show

I feel the adrenaline
moving through my veins
Spotlight on me and I'm ready to break
I'm like a performer,
the dance floor is my stage
Better be ready, hope ya feel the same

All the eyes on me in
the center of the ring
Just like a circus
When I crack that whip,
everybody goin' trip
Just like a circus
Don't stand there watching me, follow me
Show me what you can do
Everybody let go,
we can make a dance floor
Just like a circus

Can anybody hear me I'm
hidden under ground
Can anybody hear me am I
talking to myself
Saying, "tag, you're it,
tag, tag, you're it"
He's saying, "tag, you're it,
tag, tag, you're it"

There's only two types
of guys out there,
Ones that can hang with me,
and ones that are scared
So baby I hope that you came prepared
I run a tight ship so, beware
I'm like the ringleader
I call the shots
I'm like a firecracker
I make it hot
When I put on a show

I feel the adrenaline
moving through my veins
Spotlight on me and I'm ready to break
I'm like a performer,
the dance floor is my stage
Better be ready, hope ya feel the same

All the eyes on me in
the center of the ring
Just like a circus
When I crack that whip,
everybody goin' trip
Just like a circus
Don't stand there watching me, follow me
Show me what you can do
Everybody let go,
we can make a dance floor
Just like a circus

Can anybody hear me I'm
hidden under ground
Can anybody hear me am I
talking to myself
Saying, "tag, you're it,
tag, tag, you're it"
He's saying, "tag, you're it,
tag, tag, you're it"

(Let's go) Eenie meenie miny mo
Get your lady by her toes
(Let me see what you can do) If she screams, don't let her go
Eenie meenie miny mo
Your mother said to
pick the very best girl
And I am

(Both, simultaneously)
Running through the parking lot
He chased me and he wouldn't stop
Tag, you're it, tag, tag, you're it
Grabbed my hand, pushed me down
Took the words right out my mouth
Tag, you're it, tag, tag, you're it
Running through the parking lot
He chased me and he wouldn't stop
Tag, you're it, tag, you're it
Grabbed my hand, pushed me down
Took the words right out my mouth
Tag, you're it, tag, tag, you're it

(All eyes on me, in the center of the ring
Just like a circus
When I crack that whip, everybody gonna trip
Just like a circus
Don't stand there watching me
Follow me, show me what you can do
Everybody let go, we can make a dance floor
Just like a circus
All eyes on me, in the center of the ring
Just like a circus
When I crack that whip, everybody gonna trip
Just like a circus
Don't stand there watching me
Follow me, show me what you can do
Everybody let go, we can make a dance floor
Just like a circus)

...

Kas put his keyboard away, and the two left the training hall. He went to the faculty lounge, and invited the teachers to see him and his sister go at each other at full force.

...

Two hours passed, and the only people who followed Kas and Kyra were Wayne, Emma, and Gloria. They walked to a field a bit far from the walls of Randall, and prepared to fight.

The two siblings began to have a very powerful and fast battle, quite similar to the way they fought in the training hall. Emma, Wayne, and Gloria were protected with a powerful barrier, then heard someone coming their way.

"My brother always knew there was something sketchy about you, sir."

The teachers turned around to see Katie with a notepad and pen in her hand. Kyra approached her, and used a spell on her to make her forget about the fight. She then told Katie to go home, which she listened. Everybody was then teleported to the choir room

There, the five would all do a song Kas played on his keyboard.

Wayne Kyra Kas Emma Gloria

(All) Stay
(All) Stay

(All) I saw this dream so many times

(All) Unable to reach you no matter how much I reached out
I always grasped only air
(No no no no)

If we could be at a distance such that I could touch you if I wished
If I could be reflected back in those eyes
If you could be there

I will dedicate the beginning and ending to you
Throwing away this illusion....I cannot go back anymore

(All) Just be in sight
My body is hot and the wind is strong
Looking at you
My heart is being burned by these strong emotions

A truth that (we) cannot look away from
I want to discover that with you

(All) Just be in sight
This heart is always a part of you
Stay
Stay
Stay

In this endless darkness (in this darkness)
When all I can picture is just you
My pain disappears (crash crash crash crash)

Though we may have walked through different days
Didn't I always reach these your eyes (ever)
Because you are here

The sadness that you have sealed away and your deep resolutions Share it with me...share anything and everything with me

(All) Just be in sight
Tomorrow is still far away and the shadows are beginning to crawl
Looking at you
M strong wish will remove any hesitation

The truth that I hold in my heart
Belongs only to you

(All) Just be in sight
This heart is always a part of you
Stay
Stay
Stay
