Hey while we have some one well versed in Index musicness. Could you try and find out what that song with the drums that plays near the end of the Koruko vs Awaki scene in episode 7? (Index Season 2 obviously) It plays just before and during the part where Touma comes up to rescue her. (the end part where Awaki tries to teliport out part of the building in an attempt to crush Koruko from the remaining part of the building falling on top of her)
It's not in the OSTs that I've found and I don't know what the name of the song is.
