Can you suggest me manga in which one or two character have high fever, that they feel really awful/sick/have nightmare. I prefer if the fever is caused by injury, poisoned, heat stroke, etc. Not just from common cold that will be fine after sleeping a day or two.

Except hentai, yuri, shoujo ai & ecchi, I'm fine with other genres. Manga with good plot is better.

Thank you..

I remember something like this happened to in Blade of the Immortal... I don't really like that manga so much, but still. I hope you get more recommendations, for some reason I like those kind of scenes.
