Yumiko Sakaki 榊由美子

A second-year at Mihama Academy, and the daughter of the East Beach Railway Express Group tycoon. She was the first student to enroll at Mihama Academy. She has waist-length black hair. Because of her bluntness and hard-to-please personality, she has difficulty talking to others. Always trying to be alone, she hardly spends time with the others. She always carries a box cutter with her and use it to threaten others when she’s angry. She is a bookworm, and mystery novels are her favorite genre. Although she gives off the aura of a spoiled princess, she loves junk foods, and a cup of fried soba noodles is her favorite meal. Her representative fruit is grape.
