About NinNinDays
NinNinDays is a story about a modern-day ninja who saves Sumire, a young woman from a hidden mountain village, after she collapses from hunger on the road to the city. She then moves into the protagonist’s home as an uninvited guest, determined to repay the debt of saving her life.
Sumire’s story
Ninja have worked as mercenaries in the shadows throughout history, carrying out espionage, plotting and assassination for daimyo and feudal lords. In the present day, the village where their descendants live has dwindled to a small group of houses in the mountains because requests for work have become scarce. Its tradition still sends young ninja away to train, and Sumire’s father, the village chief, orders his only daughter to leave for the city.
Sumire already has the qualities, abilities and knowledge of a ninja, but she is a natural klutz who often makes mistakes. She leaves the mountains without food or money and collapses from hunger before the protagonist finds her. She loves to eat and is always pigging out.
