Kaori Sawahara

In the manga she’s just a supporting role that screams lot and is rather a scaredy-cat. She’s Tadashi’s girlfriend. She’s got an unusualy extremely sensitive nose and becomes very jealous when Tadashi is near other women. Due to her overly sensitive nose, she seems to be able to sense when the creatures are coming.

She’ll die while trying to reach out for Tadashi.

In the anime she’s the main role and acts totally different in contrast to the manga. She’s Tadashi’s fiancé and girlfriend. She deeply loves him and wouldn’t even mind dying for him.

Later it’s revealed that she’s got a unique immunity against the germs and survives with a small group of people.
