>>1672678Gotta go against the idea of invisible clothes. Seems too much like Misa's story (the character, not the author).
I would have to say C: Chikane was cured of her invisibility. However, the exposure to so many chemicals in such a short amount of time has left a disastrous side-effect on her body.
Personally, I'm torn between the effect being:
A: Her skin temporarily becoming super sensitive and irritable, in the sense that if she wears anything that comes too close into contact with her skin causes an unbearable burning sensation. The effects are lessened the more her skin is allowed to breathe, however. This forces Chikane to either find some *extremely* skimpy outfits to wear home, or just do without clothing.
B: She develops a temporary allergy to synthetic fibers, notably polyester. Wearing them would give her a terrible rash. Problem of course being that her clothes (and most of the clothing in the school), is made with polyester cloth. Chikane would have to scourge the school to find something made of natural fibers like cotton, or just deal with the rash.
