Kikoru is a very talented cadet who has super strength as well as speed. She can use her armor to heal injuries as well as fire off powerful blasts of energy. Still, that won’t be enough to defeat a demon lord. Milim’s strength seems to not have any limits and her energy projection is on a whole other level. Mix that in with her natural flight and it won’t be easy for Kikoru to get anywhere near Milim. You can’t win if you can’t keep up and Milim should end this with a solid blow. Milim wins.
