What song is played when Ace is questioning why everyone came to save him in episode 468? In One Piece episode 468 around 6:38, there's a song when Ace is questioning why everyone came to save him. The song sounds like a Gregorian chant.

I tried going through the soundtracks but I couldn't find it. 

What is that song?
