Arisa is a "yankee"(a yankee is basically a gang who likes to beat people up for fun. Basically a bully) who is friends with Tohru Honda and Saki Hanajima. She used to idolize over Kyoko Honda because she was known as the "Red Butterfly"(her name comes from when she rides her motorcycle through the night, her lights look like a butterfly), but was disappointed when she found out that she was a dotting parent over Tohru. She likes to tease Kyo because she believes that Kyoko would do the same if she was still alive.
