“Yokai Ninja ~ Ninja Monsters”

2025 Edo Shogunate: Japan refused to interfere with other countries and continued to isolate the country for more than 400 years.
For the peace of the country, the powerful youkai and the ninjas…two shadows!
Japan has developed rapidly until 2025 due to the “human pillar system” that is built on the sacrifice of life.
A ruthless “human pillar” notice that has arrived at the “Kanafushi family” who lives in peace…
From there, the gears of fate start to move!
Full of hot battles of ninjas who fight by “motivating” youkai, and human dramas that shake the hearts of the viewers!
