That's why I used the word "passable" in terms of combat ability, because while she could fight unarmed she was still worse than Shiho. I will list some of the things that will hinder her abilities but not all because that would take a while...
In hindsight, when I decided on a teleporter Esper as a character, Aoi was one of two choices... The other was Minami Azuma
I chose Aoi over Minami because Aoi was just a much nicer and more sociable a person and far better suited to a roleplay with this atmosphere... And seeing how you reacted with Aoi... I don't think Minami's ability to teleport things to many many miles away while at the same time being a very good combatant and martial artist would have given her much favors...
