From the Hetalia KitaWiki:

"Belarus is an intimidating, harsh young woman who radiates a hostile atmosphere. She has a deep infatuation with her brother Russia, though her feelings are not returned and he feels disturbed by her deep obsession with marrying him and her somewhat stalker-like behavior. Latvia said that she and Russia are so scary that even ghosts wouldn't want to meet them. She's said to have a very strong heart and equally strong will, but they only seem to manifest in negative ways. She's rather vulgar in her speech, and was noted to say things like "penis" and "shit" in a calm way."
