Yumiko Sakaki is a second-year student at Mihama Academy. She is the daughter of "East Beach Railway Express Group" tycoon, Michiaki Sakaki.

After Mihama Academy had been established, she was the first student to enroll. Her defining feature is a waist-length black hair. Because of her bluntness and a hard-to-please personality, she often comes into conflict with her classmates. Always trying to be alone, she hardly tries to get along with others. She always carries a box cutter with her and uses it to threaten others, particularly Yuuji, when she gets angry. She reads so many books that she’s called a “Bookworm”, and she especially loves mystery novels. Although Yumiko is such a lady, she changes completely in lunchtime; junk foods, like a cup of fried soba noodles, are her favorite dishes

Her representative fruit is the grape.
