Hashimoto. A Japanese House cat, Tells a sad story about why Cats are polite to mouse, Which involves American Cats in luxury and Japanese Mouse in luxury, While Japanese Cats are forced to work in backbreaking, physcial labor. Which wasn't the case as Mice and Cats once lived in "perfect" harmony. Which basically meant that mean cat bosses treated mice like crap, but all was good until Hashimoto defeats Tachibana, A Cat wrestler who is the most popular Sumo wrestler in all of Japan. Which causes the cats to try to defeat Hashimoto in a Ju-Jistu match but fails. And hence why Cats are slaves and Mice are bosses.
