Megumi Takani is from Rurouni Kenshin anime and manga. After losing her family in the Boshin Wars, she was taken to Tokyo to study with a doctor. Unfortunately, her mentor was allied with an odious businessman by name of Kanryuu Takeda who coerced her into making opium.
She was rescued from her situation by the Kenshingumi, and now lives at the Gensai Clinic, studying to be a doctor.
She is a kitsune -- fox spirit, and true to mythological stereotype, she is tricky, sexy, outrageous, and volatile.
