Fuma Kotaro the 19th: House of Ninjas character explained

Fuma Kotaro the 19th is one of the primary antagonists in House of Ninjas season 1. Takayuki Yamada plays the character on the show.

The shinobi world of House of Ninjas consists of ninja clans that have existed for long and have been serving their lords and protecting the nation working from the shadows. 

One of these clans is unlike the other. The Fuma clan serves no lord, but a cause, whatever it may be. 

They have been much more militaristic and radical in their pursuit of the goals their ancestors set out to achieve.  

Fuma Kotaro is a regnal name that each new successor of the clan’s leader is bestowed during their ascension ceremony.  

Shikkoku, a clever and a bit deluded member of the clan, becomes the 19th Fuma Kotaro and proves to be the clan’s most effective leader yet. 

Becoming the 19th Fuma Kotaro

Shikkoku is the original name of Fuma Kotaro the 19th. He would change things around after becoming the leader of the clan. 

He started Gentenkai, a religious group that goes on to have more than 30,000 followers and growing. 

It is actually a cult that he leads while assuming a new identity, that of the enigmatic and godly Tsujioka Yosuke. 

He plans and executes while using Gentenkai as a front.

Under his leadership, the Fuma clan managed to infiltrate many fields and even secure high and powerful positions. 

The past

Six years ago, he was just Shikkoku, a Fuma who was swiftly defeated by Haru Tawara, who eventually spared his life when he continued to beg and plead with him. 

Not too long after that, Shikkoku stabs Haru’s older brother Gaku and throws him into the ocean.

However, he actually saves Gaku and later influences him to defect to his side and clan. He changes him ideologically as Gaku realizes what he must do and who he must serve.

His plan is to overthrow major powerful figures in the country’s political sphere as well as national forces.  

Shikkoku says it was Haru giving him a second chance that changed him completely, to the point that he created Gentenkai and became a sort of self-proclaimed god. 

Delusions & death

While a competent leader and a highly influential one as well, Fuma Kotaro the 19th also loses the plot a bit in his pursuit of the Fuma’s ancestors’ desires. 

He buys into becoming the god who can’t be killed by a mortal a bit too much. 

When Haru cuts his limb off in a climactic battle, he mindlessly tries to reattach it to his body, while mumbling he’s a god. 

Soon, those delusions come to an end and Gaku deals him the finishing blow after getting defeated by his brother because he doesn’t want Haru to start killing now when he’s managed not to thus far.
