IINE (So Good)
Tick tack tick tack my heart beats.
I can’t stop this feeling running wild.
Tick tack tick tack my heart beats.
I can’t stop this feeling. I screamo.

[Hey, it’s my afternoon snack!] [Wait. Wait. Wait. Don’t take it in advance of me!] [[???]] [[All yours are also mine.]]

I was left alone. I looked up the sky.
What a sentimental night!
I’ll go, driven by this feeling,
running away from the reality.

So good. So good.
The party under the night sky.
So good. So good.
I’ll go brilliant.
That for now, moshing up.
Taking little by little is impossible.

Yeah, yeah.
It’s too transcendental. It’s perfect.
A gal must have
a dream which is surely
super-chaotic.

Sway your head! Take off your glasses!
Swing your head! Take off your glasses!
Sway your head! Take off your glasses!
What a jammed, bursting, over-packed rucksack.
Take it off right now!

Yo! Yo! Yo! Yo!
[The microphone check. One, two. One, two.] [Are you ready to mosh?] Are you ready to mosh?
Put your fox sign up!
[It’s a fox sign, you know?]

[[It’s not a maloik sign but a fox sign.]] [[Not a sign of the horns but a fox sign, you know.]]

Gyah!

I pledged to myself by linking my little fingers.
What a sentimental night!
I’ll go, driven by this feeling,
running away from the reality.

So good. So good.
The party under the night sky.
So good. So good.
I’ll go brilliant.
That for now, moshing up.
Taking little by little is impossible.

Yeah, yeah.
It’s too transcendental. It’s perfect.
A gal must have
a dream which is surely
super-chaotic.

[So good. So good.] Yeah, yeah.
[So good. So good.] Yeah, yeah.
[So good. So good.] It’s super-chaotic.
Yeah, yeah.
[So good. So good.] Yeah, yeah.
[So good. So good.] Yeah, yeah.
[So good. So good.] [So good. So good. So good. So good.]
