Ninja Kunoichi Sumire Dark Elegance

Kunoichi Sumire is a ninja specializing in ambushes.
One day, under the village elder’s command, she is ordered to infiltrate an organization engaged in human trafficking and obtain its client list.
After infiltrating the group, Sumire carries out ambushes one after another, steadily advancing her mission. Everything proceeds smoothly until she reaches the vault, as the elder had informed her.
She opens the safe and checks the list—only to find a false record,
completely different from the information she was given.
Could this be a trap?
