那岐沢 千砂

A very nice and kind onee-san in her twenties who is the waitress leader of the Daybreak Cafe. Always a very good advisor. She learned to make good coffee during one of her previous part-time jobs. She was very bad at first, but has since been a specialist in coffee making (but she isn't particularly fond of coffee).

She often deals with expelling Oikawa from the Daybreak Cafe because it is "a pervert who frightens the customers". Oikawa ended up nicknamed her the "Maiden Witch".

She also is the senpai of Umi and Sonya at the Daybreak Cafe./
