Someone who has actually played FE can supply the names, assuming they aren't just generic Pegasus Knights rather than specific characters. Some research got me thinking Paola and Katua but I can't confirm.
This one's a stumper. Nevertheless, they aren't from Blazing Sword. Could either be Paola and Katua (though her hair is usually blue) or Misha and Karin. Or it could be any two of the green haired pegasus knights together. Who knows.
