Hare (known as Ham in the Japanese) is one of the seven Searchers, the main protagonists of the anime series. He is the last monster to join the team, after Genki and Tiger enter a monster battle in the city of Aurora to win some prize money. Hare is by far the smartest of the group, but also the most cunning. He is easily tempted to be selfish or do things purely out of his love of money. His shifty nature often puts him at odds with Tiger, who seems to never have forgiven him for cheating in their first match.
Hare is very skilled with an abacus, and, once the Searchers trust him a bit more, he becomes the accountant for the group.
