Rika is a tall female Lamia and is the older sister of Ako. She has long red hair, green snake like eyes and wears a white bandana and a seductively loose shirt with the sleeves rolled up. Although she appears beautiful to look at her body language emits a strong signal that says 'don't get too close for your own good'. She has a cigarette constantly perched in the corner of her mouth that doesn't appear to be lit.
