Seiko is a quiet and timid student, who is very reserved. As a pharmacist, she has an extensive knowledge of medicine and drugs. She creates many different kinds of drugs. Seiko is shown to be somewhat pessimistic. She was conscious of how easy it was for people to guess what she was thinking through her facial expressions, so she hid her face behind a Respirator Mask. She has pale grey tangly hair, purple eyes, and braces. She is the Ultimate Pharmacist at Hope's Peak Academy. 18 y/o.
