WoF-Chikai no Yami lines

Inspired by Sei no Yami by Irino Miya, who voices Est. Lyrics here. The translation made this song for me. Initially, I'd thought that this sounds too un-Est-like to be good, but then I saw those lines about red chains and angels (and redemption) and my heart... <33

Please, look at the English! Maybe you'll see what I saw. Ctrl+F "Irino (Miya)" or skip to the bottom.

Est Rinaudo from Otomate's Wand of Fortune.
