This is my interpretation of the song Knock Out by Taiiku Okazaki which honestly fits with the fanfic
[Verse 1]
Step in, heels on, adrenaline is my muscle
Noradrenaline is my drug like any everyday
Always asking for my roaring instincts,
What I want, in other words, dopamine for my brain and organs
[Verse 2]
Swiftly unleash metaphysical techniques like a power ranger
Rinse and repeat the process until I grasp the image
To those who annoy me, I'll leave them with a bonk to the head, and scream "KNOCK OUT!"
[Pre-Chorus]
No powers, no origin,
I am simply me
[Chorus]
I want to say something, let me say something, I want to tell you something,
Something like not hesitating with the fist you thrust forward
Abracadabra, so loud, please shut up
Physical all-out, My MP is zero
Dealing with your HP until it hits zero
And when I'm done, let me just say 'good night everyone'
[Verse 3]
Training hard until I blackout, there is no such thing as a timeout
Don't look for any excuse, seize the opportunity, it's time to stand out
If I use my head, I'll pierce through the chaos with my own hands,
What I want, in other words, is a good start for today and tomorrow
[Verse 4]
Literally, a variety of colorful heroes
Emulating them since my childhood days
To those plotting something evil, I'll leave them with a bonk to the head, and scream "KNOCK OUT!"
[Pre-Chorus]
No tricks, no fakes
It's all me
[Bridge]
Carrying on with my muddy soul
Every day my courage grows strong
Stand up, you are already reborn
Just be you
[Chorus]
I want to reach something, let me reach something, I want to achieve something,
Like warmth, love, bouquets, and things like that
I want to say something, let me say something, I want to tell you something,
Something like not hesitating with the fist you thrust forward
Abracadabra, so loud, please shut up
Physical all-out, My MP is zero
Dealing with your HP until it hits zero
And when I'm done, let me say just 'good night everyone'
