Isami Eimi

A hamster raised in a lab who'd run tests for the greater good of mankind. Classified as a special specimen, Eimi was studied for her abnormal ability to regenerate tissue at alarming speeds. After a test went wrong, Eimi was granted the opportunity to live out her brave hamster adventures as a bright-eyed, living breathing girl! The possibilities before Eimi expanded, and as she realized she needn't be confined to the wired walls of her old cage she set off to find what wonders the world offered her!
