Oh god... Her boobs seem to make up half her body weight, which I assume is why she has no energy left for teaching, thinking, or possessing a personality. She is more like a permanently exhausted decorative object who somehow wandered into a physics classroom and was handed a salary...
And yes, despite the manga working extremely hard to convince me otherwise, I do not find her attractive. At... all...
There is literally nothing appealing about her. She seems to generate a force field that repels me on contact, which is at least the first convincing piece of physics associated with her.
