What's The Name Of This Place? (Intro)

What's the name of this place?
Monster Island
Monster Island?
I've never heard of it
There's no such real place called Monster Island

Oh no, no, no, no, no, no, no, no
Oh, grandfather
What's the matter with you, my child?
A monster, a monster will set fire to the city
And trample on the people who try to run away
What? A monster?

It is impossible to anticipate where the two
Monsters which suddenly appeared will attack next
M-M-Monster, M-M-Monster, M-M-Monster Island
No human being can understand that
The monsters on Monster Island can understand it
