House of Ninjas

The Tawara family seems just like any other family on the outside. Souichi, the dad, has been running the family's sake business for a long time. But he's worried because it looks like there's no one to take over after him. His three kids, Haru, Nagi, and Riku, don't seem interested in the business.

Haru, the oldest since his brother died six years ago, is the family's main hope. But he's more into his job filling vending machines. Nagi, his younger sister, is in college, and the youngest, Riku, is still pretty young. Haru lives with his mom and grandma.

What most people don't know is the Tawaras are the last of a ninja clan. They started living as normal people after a family member named Gaku died tragically.

When a group starts causing trouble for the country, the government turns to the Tawaras for help. They don't want to at first, but they end up agreeing to help with the mission.
