This song is about the fans (Hackers) (1 Viewer)

Nao is drawing strength from this song, maybe actually from the fans. She possibly is talking about her depression. @Hackers

Whenever I feel like I'm losing it, I always think of the place where everyone is there.

comment from a fan on reddit:
Never really properly analyzed the lyrics but it's definitely a song for the fans. In the video at 3.20 Nao says "watashitachi to antatachi no tame no kyoku wo..", literally "(we're gonna play) the song (made) for you all and us". Notice that "no tame" indicates a purpose, so the song is literally made for the fans and for themselves. For the bond they have.
At 7.12 Nao's line is "Kono mama isasete kure...kimi to ", something like "Please, I want it to be like this forever...with you". Well, this is the original line but here in the live she actually says "koko ni iru, minna to!" instead of "kimi to": "we're here, with everyone!". She always change that line live. In the new Zepp Haneda she says "Kono mama i..isshou ni iyou yo! Minna to!", which means "Let's say that together, everyone!".
I will try to analyze the entire lyrics someday but it's definitely a love song for the fans.
Edit: noticed a big mistake. The line in Zepp Haneda means "Let's BE together, with everyone!"
