I'm just gonna put up the lyrics for the ballad Iwasawa played at the end, ofr everyone. Maybe it might have some answers as to why Iwasawa disappeared.:

Spoiler for Japanese Lyrics:

Joushiki butteru yatsuga warrateru,
Tsuugi wa donna uso so tsuku?
Sorede erareta mono?
Daijini kazatteokeru no?
hito wa sore demo susumanakya naranai
Sonna no wo utau yo
Naiteru kimi koso,
Kodokuna kimi koso,
Tadashii yo,
Ningen rashii yo,
Otoshita namida ga
Kouin wo,
Konna ni mo utsukushii
Uso ja nai
Hontou no bokuro wo
Arigatou

Spoiler for Mazui Translation:

The ones who ignore common sense laugh,
What will they lie about next?
What will be gained?
Can we hang it proud?
Man must go on regardless,
That is my song,
It's because you're crying,
It's because you're lonely,
You're right,
That's being human,
Those tears I cried
In time,
It's so beautiful,
It's not a lie,
For the real us,
Thank you

In the end she says "To go on singing like this, this is why I was born. Just as I was saved, I'll save someone else like this. Finally...I finally found it."
