Masumi is a young pup born to the moon-wolf Tsuki. She does not possess any of her mother's lunar marks, but she is unique within the pack for her greenish pelt.
She has been known to be quite charming, often using her charisma to get out of trouble. She hopes to become a scout one day.
As part of the pack's second litter, she has been blessed by the moon goddess Luna with high constitution and resistance to the elements.
Masumi is a Libra and her favorite food is pheasant.
