Sayaka Watanabe

One of the tenants at Kawai Complex and a college student studying at a local university. She basically has a cheerful and laid back attitude; however, she has a bad habit of leading on guys even when she's not particularly interested in them, which tends to get her in trouble. Mayumi dislikes her mostly for this reason, however Sayaka also likes to tease and grope her, further contributing to her dislike of her.
