Haruna Yukimura is a dutiful student, and the head of the school's student council. The girl is polite, friendly, and is enrolled in the pre-med program at the University. Some call her bossy and arrogant, while others simply consider her something of a go getter. Either way, she's always there to help her classmates, and is a very dutiful and intelligent student. Strangely enough, she does have multiple days in the year where she just..disappears. Why exactly? Nobody can tell.
