Secret Police

Composition: BuriruP
Arrangement: BuriruP
GO!
It’s useless! You’re under surveillance, no matter where you try fleeing to
We shall never let a party plotting the overthrow of the nation escape
We’ve grasped all of your action patterns, and just about everything else!
While you’re living carefree, our cooperators are increasing in number
All of the people around you- For example, your neighbors, colleagues
Even your lover and family are monitoring you
We’re the secret police, the national security department directly under the government!
Under the cover of darkness, the secret police cracks down on spy activities
And we’ll watch you from dawn ’til dusk
To force you into confession, we’ll use every method
Like repeated torture or injection of intravenous drugs
Or taking someone important to you as hostage- We won’t show mercy!
So the secret police is the national security department directly under the government!
The secret police does thought control and gathers information on dissidents
And we’ll investigate you day after day, too
The secret police is the national security department directly under the government!
Under the cover of darkness, the secret police cracks down on spy activities
And we’ll watch you from dawn ’til dusk

GO!
Muda da zo! Omae wa miharareteru doko e nigeyou to mo
Kokka no tenpuku takuramu yakara kesshite warera wa nogashi wa shinai
Omae no subete no koudou pataan haakushite iru nani mo kamo o na!
Omae ga nounou to kurashiteru ma ni kyouryokusha wa fueteru
Omae no mawari no subete no mono-tachi tatoeba rinjin, douryou
Sara ni wa koibito, kazoku made mo ga omae o kanshishiteru
Warera himitsu keisatsu seifu chokuzoku kokka hoanbu na no da!
Himitsu keisatsu yami ni magireru supai katsudou torishimari
Asa kara ban made omae o miru
Omae o jihaku ni oikomu tame arayuru shudan tsukau
Kurikaesareru goumon arui wa joumyaku chuusha no yakubutsu
Arui wa omae no daiji na mono o hitojichi yousha wa shinai!
Dakara himitsu keisatsu seifu chokuzoku kokka hoanbu na no da!
Himitsu keisatsu shisou danatsu fuman bunshi o torishirabe
Kuru hi mo kuru hi mo omae o miru
Himitsu keisatsu seifu chokuzoku kokka hoanbu na no da!
Himitsu keisatsu yami ni magireru supai katsudou torishimari
Asa kara ban made omae o miru
