this doesnt work, you cant be allergic to a girl physically, its a mental thing, in otherwords you will get hives being around anyone you believe to be a girl, regardless of their actual sex.... so he would still get a reaction from Nishino because his mind will be like "oh shit its a girl" and his body will be like "oh shit time to bust out the hives" ...... why does nothing/nobody ever get this condition right?
