Tomiko Asahina (朝比奈 富子 Asahina Tomiko) is the head of the Ethics Committee and the grandmother of Satoru Asahina (more precisely 9th level ancestor).


Tomiko has wavy neck-length dark-grey hair that is swept to the left side, deep blue eyes and she appears much younger than her age due to her ability to regenerate her telomeres through use of cantus.

Tomiko is seen to only wear kimonos, a traditional Japanese dress.

About 245 years ago, she had ash brown hair. During her occupation as nurse, she wore an outfit which consisted of a sky blue dress with a white collar and white cuffs, a white apron with a left pocket, and a white bonnet featuring a red symbol. On her left sleeve there appears to be embroidery of the same symbol.

In the manga, this outfit was quite different. She appears to be wearing a solid scrub top with sleeves that end above the elbow and a Peter Pan styled collar. She also wore scrub pants that end above the ankle, a nurse's cap, and nursing shoes. All of these were lighter colors.

Biography & History

In her early adulthood (relative to normal human age), Tomiko was a nurse in a town's hospital who is one of the survivors of K's Karma Demon incident and the only person from the previous era still living. As a result of the incident the Ethics Code was revamped, ushering forth a new era. Several decades later she was made Head of the Ethics Committee and remained in the post for over 170 years.[2]

Tomiko intends for Saki Watanabe to succeed her position as she possesses a strong mental stability as well as qualities of a leader. Because of this, she had asked the Board of Education not to dispose of Saki and her friends despite knowing about the true history. She also revealed that they were responsible for erasing their bad memories of the past to protect the minds of the townsfolk. In addition, she ordered an experiment on Group One, in which mind alteration is relaxed and its members granted more free will, in hopes of creating the next generation of leaders. Unfortunately, this free will resulted in Mamoru Itou and Maria Akizuki fleeing Kamisu 66 and their offspring almost bringing human civilization to ruin.


Although Tomiko's cantus usage was always perfectly average during her time in Sage Academy, she possesses one ability that no one else but her has ever known to have; The generation of her telomeres (Parts at the ends of human chromosomes. Every time a cell divides, its telomeres are shortened a little, as they cannot be fully regenerated. Once the telomeres have worn down, the cells lose their ability to replicate and death is inevitable. Therefore, the length of our telomeres dictates the length of a human's lifespan) through using cantus. With the ability to regenerate the telomeres in her cells, Tomiko managed to extend her life, having lived for more than 250 years[2]



  • The name Tomiko means "wealth, abundance" (富) (tomi) and "child" (子) (ko).
  • Tomiko's surname Asahina means "morning" (朝) (asa), "ration, proportion" (比) (hi) and "apple tree" (奈) (na).


  • Despite her look, Tomiko is 267 years old and she has been the committee head for 170 years, at the time when Saki Watanabe and her friends are 14.
