Seeing the flying humanoid demon was literally flying to get away from the humanoid base, Blake quickly made his decision.
"Cyra! Help me fly!" Blake shouted as he ran towards the little demoness.
"Okay!" Cyra then caught Blake's running body before creating a huge explosion downward, sending her and Blake flying into the sky.
Just like how Blake was chased by Vera when he glided with his wings, Cyra also used the explosions, which were now stronger using the dark flames to catch up to the wounded flying humanoid demon who was running away from the humanoid demons' base.
The flying humanoid demon was certainly fast with his wings, but it wasn't unreachable with the flying humanoid demon in a wounded state and Blake was flying with Cyra and her improved, stronger dark flames.
