Yowane Haku came to represent an aspect of failure within the Vocaloids, illustrator Caffein portrayed her as a DTMer, a person who uses the Vocaloid program but has not mastered it and is thus stricken with grief and disappointment at their lack of talent. The fandom displays her personality mainly as a depressed introvert, and at times lonely. It should be noted that there is little to no portrayals of Haku as a mean drunk.
Other aspects of Haku is being a failed Miku or a crier due to her failures. It is not uncommon to see her drawn with tears in her eyes, whether she is happy or not.
