Satsuki Mujika (ムジカ皐月) is a wandering swordsmith who travels with Master, a penguin-like animal companion in search of the 100 Demon swords which were stolen by an unknown assailant and destroy them.
Satsuki is a teenage petite woman with scarlet hair and brown eyes. She wears a simple sleeveless kimono, long arm gloves and sandals. She wears a rolled up comforter strapped across her back. She has her Wakizashi, strapped on her left side of her hip.
Satsuki is a carefree young girl who has a love of dango and swords. She is analytic of swords' attack power and can identify them. Satsuki is willing to help people as she immediately offered herself as Jirou's bodyguard to oust the Wolf Family from the lodge. She also has late reactions to embarrassment as shown after defeating Wolf Monkey in a fight, she shortly noticed her chest exposed and covered them flustered.
Traveling on the road hungry, Satsuki and Master smelled dango deep in the mountains and encounter Jirou who was surrounded by a pack of wolves, which she defeated them easily with the samurai's sword she borrowed. After that, Satsuki and Master chowed on Jirou's dango and introduced themselves to the bewildered samurai and explained of their travel around the land in search of the 100 Demon swords and destroy them. Sensing another danger in the forest, the group decided to head to town for rest and food.
At Pelican Inn Lodge, Satsuki and Master finds the town to be in a state of poverty due to the Wolf Family's forced monopolization of the lodge's livelihood from Jirou's account. Satsuki offered to help Jirou and immediately attacked the Wolf Family's estate where she easily dispatched the henchmen and soon faced Wolf Monkey. After introducing herself and stating her intentions to the Wolf Family's head, Satsuki was struck, only for her clothes covering her chest exposed much to Master's and Jirou's shock and the mogul's pleasure, revealing Wolf Monkey's sword to be Bare Naked Nymph, one of the 100 stolen Demon swords. Unfazed, Satsuki proceeds to draw out her Wakizashi and used Demon Sword Reversal Starbiter Forge to increase her weapons' length to a size of a katana and its attack power to 1500 enough to break Wolf Monkey's Demon sword and won. After her victory, Satsuki noted her weapon's current attack power isn't yet enough to destroy other 99 Demon swords before noticing herself still nude, much to her embarrassment. Wolf Monkey attempted to strike while her guard is down but Jirou saves her in the nick of time.
After restoring Pelican Inn Lodge back to its normal state, Satsuki and Master continued traveling on the road again after receiving dango as a reward and bluntly asked of her master's motivations to create such a perverted sword.
