Laughing under the Clouds

Kumo Brothers take on the duty of eradicating "evil" during the Meiji Era and also preventing Orochi (giant snake) to come back which is said to possess overwhelming strength and only appears once every 300 years. Its appearance itself is a sign of calamity and therefore Yamainu army want to seal Orochimaru's power for the sake of peace in Japan. On the other hand, Fuma Clan want to control Orochimaru so they can overthrow the Japanese government.
