Hange is usually seen wearing a red track suit with a white tag on the front that has "Hange" on it, a white lab coat, and a pair of oval shaped glasses. Hange has light brown eyes and brown hair that is thrown up in a messy pony tail and is always paired with a non-fading grin.
Hange is very enthusiastic and fixated on studying Titans; namely Sawney and Beane, the Titans that Hange caught and tied up. While Hange is a very smart individual, the Titan experiments take up all the money and allowance that comes Hange's way.
StoryHange views the first-year entrance ceremony from inside a classroom. While Eren and the gang find themselves in the Scout Regiment, Hange shows up with Titan nail clippings found in the trash earlier. After being introduced, Hange provides a way to call Levi to Eren by handing him a plastic bottle and ordering him to throw it in the trash of biodegradables. 
- Levi - Hange enjoys sharing Titan data or knowledge with Levi, who explicitly shows that he is not interested. Regardless of his attitude towards these interests, Hange likes poking fun at him and getting a reaction, but Levi ends up besting his companion more often than not. It appears that the two of them are close friends dating back a few years.
