English:

40 people, counted roughly. Everyone's eyes are alert
However small the sin may be, it's not going to be overlooked
Softly hold your breath, keep on looking around you
Once your [bad word] out, it's over, classroom of snitch eyes

Yes, you've got to hide your [bad word] feelings. Throw off the others.
It's for me to be the lone survivor!

Now! Now! It's time to squeal! I'm going to tell teacher!
Look, look, this many bad kids, one・two・three・four
Now! Now! It's a massacre! Bad kids are thrown out!
Until the last one is decided, it won't end

bit diminished, 30 people. The classroom is a closed space
The tension starts [bad word]  it makes me excited

I found one again today!
This huge fool got his tail out, throw him out
Everyone from the blacklist class

Now! Now! It's time to squeal! I'm going to tell teacher!
Put a scalpel to the insane head
Now! Now! Another one is gone now
Until the last one is decided, it won't end

Oh my, there's none now? Number of classmates: zero
Now! Now! It's a massacre! Let's be done with the teacher too!
Until the last one is decided, it won't end
