Seraph I dont know how or why I missed this comment ππ im sorry! but it perfectly summarises everything I need to know! Appreciate it :) So erm.. does that mean Ryoko's soul has passed on? And were there S1 OVAs?

Durandal and Nehustan annihilated each other in the end.
Fine's soul can reincarnate in any of her descendants' bodies if they are around an aufwachen waveform (the waves given off by relics). Ryoko was one of her descendants, which is why she became Fine when Tsubasa first activated Ame-no-Habakiri.
The song during the ending is the song Kanade and Tsubasa sang in the first episode, "GyakkΕ no FlΓΌgel".
The explanation for why they had to fake their deaths and keep everything secret for 3 weeks is explained in the Symphogear G OVAs, which I recommend watching after you finish Symphogear G.
