Kio learn how to fight more efficiently, running away from the enemy just mean you can predict their movements and you can prepare to attack or evade better, in dota game i think it was called juke or juking
Gundam AGE-3 Fortress has some heavy firepower, and looks like that pink haired teacher of Kio is a vagan spy from the impression i got on the next episode preview
P.S. the animation on the mecha fights on this last generation arc is consistent, im loving it
