From what im reading D) would be best option for her survival.

The Nova Dragon aint a dog. You cant just try to give him food.
Those phantom dogs could be easily delt with by using Holy.
While the Nova Dragon can focus on ayame.

I do not chase, it would be stupid for any spellcaster to run after a melee.
While the part where Ayame would be upside down would give possibility to throw stuff at me could work it is unlikely that it will. The reason for that is it mostly likely is impossible to aim as the object would be affected when it pass between the two diff. gravity. There again it would give me the advantage as i need to aim still but most of my spell and the one of my Nova Dragon cover a big area making the aiming much less relevant.

She will have to get on my level to have a chance to beat me and it still gonna be her downfall.
