Did you get your answer?

OnCollisionstay(Collision coll)
{
youreTouchingMeOniChan = true;
}

FixedUpdate(){
youreTouchingMeOniChan = false;
}

if this weird named variable is equal to false then the loli is safe. Nothing is touching her.
with that you can keep track if something is touching her on your code at any given time. You can also do

OnCollisionstay(Collision coll)
{
if(coll == null){MyLogicHere}
}
