There's a secret track at the end of the song
Panty: Hey Stocking! I heard our anime Panty & Stocking with Garterbelt has got the green light for a sequel thanks to its popularity!
Stocking: What? Who the hell decided that?
Panty: Speaking of a sequel... how about a trilogy? Hell, let's go further! We will reach season one hundred! A Hollywood remake is not a dream!
Stocking: Hey wait, Panty!
Panty: In fact, this planet is too small for us! Panty in the space! The whole universe will be calling my name!
Panty: So when will it start?
Stocking: How should I know, shitty bitch!
Panty: Coming up next, Panty & Stocking with Garterbelt Season Two!
Stocking: Wait! I told you it hasn't been decided yet! But, practically speaking, it's up to director Imaishi now, right?
