Levi is described to be a "clean-freak" by those who know him on a personal level, as he prefers his environment to be spotlessly clean. He is averse to having either his person or his equipment soiled, and has been known to wipe down his blood-smeared blades while still on the battlefield. However, he will not hesitate to touch filth if he deems it necessary.
Despite this clean-cut image however, Levi has an abrasive and unapproachable personality. His manner of speaking is rarely polite, and he often makes alienating comments that are coarse or inappropriate. His dark brand of humour, always delivered in deadpan, ranges from rude to outright vulgar. He tends to phrase things in a brash and insulting manner, and is not above provoking his opponents or belittling anyone who irritates him. This often unsettles people and makes him difficult to be around.
