Okay, so going off what I am seeing, Kikoru has a monstrous skill advantage, able to hold her own against the likes of Gen Narumi whose precognition is broken, so in a close range combay, Kikoru is not going to have any trouble even with Teru having Anal Prediction (to which Kikoru has her own) and having lifting strength (to which Kikoru is used to)
There is the fact that her Accelerated Development would allow her to one-shot almost immediately as soon the match start due to how fast it is, which increases not just her physical statistics but her analytical prediction, accuracy, precision, range, piercing capabilities, senses, jumping, awareness, etc... and that isn't taking into consideration her combat techniques's Damage Boost, which makes her a lot stronger and faster to the point of one-shotting and blitzing
However, Teru does have really hot flames which would easily melt Kikoru given how hot they are but since they are not killing each other, she would probably raise it high enough to ward Kikoru from approaching her or melt her close range weapons, rendering that skill advantage in close combat moot, forcing Kikoru to employ long-ranged method, which she is just as capable with. Given how someone who is less skilled and at a lower combat power than Kikoru could
move hundreds of meters, if not kilomters in an instant to avoid an attack that had already been fired from
a foe that he was not at the level of facing against, Kikoru could move fast enough to avoid the worst affects of Teru's flames
Teru has flight options to disengage and stay away from Kikoru but doesn't seem to have much option in abusing that range with attacks besides flames, which is stated that she had help reaching the Hundreds of Meters so in order to attack Kikoru, she would need to enter her range.
