Yeah. The 2nd angel and 2nd longinus in his harem... The first was Ingvild.. There are 4 longinus girls and 2 of them will be in his harem.

I didn´t wanted her initially(then I changed my mind) for this when I saw Shin 1 I saw it as something definitive.

In Shin 1 her boobs  shone and were used to relay Ingvild song.(the rest of girls who experienced this are confirmed in his harem) Issei said that maybe was related with the girls feelings..

In other words.. That the music was relayed with these girls that like Ingvild love/secretly love Issei, I say this for elmenhilde case too who was in this battle.
