Dec 25th, 1926. The imperial era name transitions to "Kobun” and seems to herald the dawn of a new period in history.

But behind the scenes, a Japanese nationalist revolutionary group has staged a coup d’etat with the goal of restoring "the divine nation of Japan." The revolutionaries acted swiftly, seizing control of the Prime Minister’s residence, the police department, major corporations, and newspapers.

Struggling to react, former government forces initiated a secret plan to eliminate key figures involved in the coup through an assassination program known as "Yatagarasu." This covert opeation was assigned to the "Iga Clan", a ninja clan that exists today as an intelligence agency and who are also known as "Government Dogs."
