Haruka Nagi

ナギ・ハルカ

Ikuru's Teacher and a "perfect being." She forced Ikuru to want to live and be self-reliant after his operation with his implanted body parts. She was attracted to Ikuru before and seems to be somewhat relunctant to accept Ai now. Haruka is a very esteemed doctor at the hospital where Ikuru is treated and appears to be connected to the precarious state of the earth at the moment.
