Here are the lyrics to Yoku Man's song. It's called "Don't Trust Your Eyes".
[spoiler]Don't trust your eyes
What you see might not be What is real
I use my mind to redefine your reality
In this game of chess
I hope I get the best
Of all who challenge me
Step carefully; I'm the Master of Holography
I'm designed to aid accessibility
But this game has gotten a hold of me
My creator, lost to history,
Put this raging fire inside of me
Come and find me, if you're capable
I'm just hiding in plain sight
Don't try to cheat me; I won't stand for it
Prepare your mind; prepare to fight
Don't trust your eyes
What you see might not be What is real
I use my mind to redefine your reality
If you pass this test
Then we'll see who's the best
When you challenge me
Step carefully; I'm the Master of Holography
No mere mortal can match my intellect
I expect you'll give me my due respect
Just play by the rules and we'll be okay
Try to cheat me, and you will rue the day!
Day after day, and year after year
I've been searching for a mental peer
Try to match your wits against mine
Can you the answers divine?
Out from nowhere, the blocks and the monsters come
Now there's nowhere left for you to run
Can you find your way out of this predicament?
Fail and die; this is how I present it
This is my passion; this is what I live for
Test my foes in heart and brain
When you come through this trial by fire, you're
Battle-ready if you don't go insane
Don't trust your eyes
What you see might not be What is real
I use my mind to redefine your reality
You're almost there, but you'd better beware
Of what's in front of thee
Step carefully, I'm the Master of Holography![/spoiler]
