The group that was known as E-Class was having a fun time at the Pool Korosensei made for them, after they patched it up and cleaned. Nagisa then got a song in his head and decided to play the music on his phone and started Singing, getting the attention of everyone. They recognized the song as 5-1-5-0 by Dierks Bentley.

[NAGISA]: Ever since I met you girl, you been on my brain

I can't think of nothing else but you all night and day

It's like I got a first class seat up on Ozzy's train

It's driving me insane

[NAGISA, joined by KARMA and YUMA]: 5-1-5-0, somebody call the po-po

I'm goin' crazy, thinkin' 'bout you baby

5-1-5-0, just this side of loco

I'm goin' crazy, think I love you baby

[NAGISA]: I gotta get your number girl, I gotta call you up

I gotta get you ridin' shotgun in my truck

This little bit of you I've got, it ain't good enough

Yeah, you got me all messed up

[NAGISA, KARMA and YUMA]: 5-1-5-0, somebody call the po-po

I'm goin' crazy, thinkin' 'bout you baby

5-1-5-0, just this side of loco

I'm goin' crazy, think I love you baby

[NAGISA]: Cause I, ain't never felt like this, no

And I, I just need one kiss, from you

And I'll be good as new

If I don't get some of your sweet

lovin' no tellin' what I might do

Soon the music played for a little bit and the girls were dancing.

[NAGISA]: 5-1-5-0, somebody call the po-po

Think I'm losin' my mind, girl

5-1-5-0, just this side of loco

Yeah, yeah, yeah, yeah

[NAGISA, KARMA and YUMA]: 5-1-5-0, somebody call the po-po

I'm goin' crazy, thinkin' 'bout you baby

5-1-5-0, spinnin' my head like a yo-yo

I'm goin' crazy, think I love you baby

The music ended as Nagisa was pushed into the Pool and everyone was laughing.
