Terror of the Skies III
Vayu and Soleil are the ones that are smashing the flying monsters as they could easily reach them. Vayu easily swept the low-level monsters with just a swipe of his katana. A powerful blade of wind will even make the birds that are not subjected to intensified gravity become unable to fly. His attacks are not just wind though as he would create sparks of lightning with each attack as he has become a Storm Elemental which is a more powerful and rare variant of a wind elemental.
Soleil might look cute, but her flames are more powerful than ever. She can even control hotter flames compared to before as her orange dress of flames now has linings of blue flames indicating that she has become powerful as well. Vayu mentioned that her daughter is actually more powerful than him when it comes to attacking but she lacks control which is why her attacks are often spread about.
