The main character in Blue seed, a simple japanese high school girl, Momiji has been kept ignorant of her lineage or destiny by her grandmother, but nonetheless trained in traditional rituals for an unknown purpose. Btave and cheerful by disposition, her bewilderment eventually turns to a desire to fend for herself the best she can as a TAC team member rather than being passively protected.
The elder of the Kushinada twins, it was she who was sequested, studied, and hunted as the Princess while her younger sister Momiji knowing nothing of Kaede's existence led a relatively normal life.
An unlikely combo of Shinto priestess, idol singer, and flirt(!), Her traditional Japanese-style spelling casting is a supplement to the largely technological stratagies of the TAC team.
Former detective on the Tokyo Metropolitan Police Force, Ryoko is elegant and professional. She puts her old contacts to good use for th4e TAC, and seems to be the best marksman on the team...although how can she shoot so good with that kind of hair style is strange...
Brilliant veteran of the Science and Technology Agency, her specialty is biotechnology, and she is able to rapidly divine much of the biology of the Aragami through her observations and relentless experimentations.
