A student in Kisaragi High class 2-9. Lives very close to
Naomi, and generally accompanies her to and from school each day.
A free spirited, she often says or does things that take others by surprise -- though she's also easily forgiven due to her good nature and amiability.
Her mother disappeared three years ago, leaving her with three younger siblings and a working father. As such, she basically serves as head of the household.
Seiko seems to regard Naomi as a kindred spirit, and the two of them frequently have long conversations about their many dreams for the future.
