Affiliation Fujiwara House, JAPAN, Devil Realm
Mentioned in Sengoku Rance

Geppei was the chief adviser of Fujiwara Ishimaru. He brought many innovative techniques and ideas to the leader of JAPAN, from agricultural to military. However, he was best known/remembered for three deeds:

  1. The creation of Tenshiism
  2. The invention of the Yin Yang Ways
  3. The sealing of Dark Lord Xavier

His scythe is passed down through generations to the leader of Tenshiism.


Unknown to most of the world, Geppei is a Devil loyal to the Devil King Rathowm. The ceremonies he developed for Tenshiism take the souls of the deceased out of the cycle of reincarnation and send those souls to the Devil King instead. He inflated Fujiwara Ishimaru's ambition, convinced Fujiwara to go on conquering the main continent, so that the army of JAPAN could be a carrier spreading Tenshiism to the rest of the world. His invention of the Yin Yang Ways and various innovations were all a means to help him gain influence and trust with Fujiwara and the people of JAPAN. However, Xavier's Demon Army devastated the entire army of JAPAN, and utterly ruined Geppei's plan, causing Geppei to have a great feud with Xavier.

During his fight with Xavier, Geppei suffered great injuries (even for a devil) that after a few years he passed away. Prior to his death, he took on the leadership of the Fujiwara House for a while (Fujiwara Ishimaru had died fighting Xavier). Whether out of disinterest or a lack of political abilities, Geppei was unable to maintain the power and influence of the Fujiwara House over JAPAN. He spent the last of his years focused on spreading Tenshiism throughout JAPAN. So great was his bitterness towards Xavier that he also ensured the techniques for sealing Xavier would survive through Tenshiism in case Xavier ever reawakened.

Personality and appearance[]

Geppei's true appearance is alien, with 6 or 7 compound eyes around a proboscis-like mouth from which he extends tentacle tongues. Generally, however, he wears a mask giving him the appearance of an old man.

He is a talented statesman, responsible for expanding the administrative arms of the Fujiwara Clan under Ishimaru to cope with its ever expanding empire. Not only did he introduce Tenshiism and the Onmmyou arts to JAPAN, his teachings led to improvements in agriculture, the logistical foundations for large armies and even the improvement of battle tactics.

He was also very ambitious. It was not Fujiwara's ambition but Geppei's to conquer the continent, and he had the silver tongue to convince his lord.


His combat abilities were impressive in the human world but not stand out among devils. Although as a devil he would be more durable than humans and should even be able to harm demon lords through their invincibility field, Xavier's offensive against Fujiwara unravelled his ambitions giving him no option to succeed. In a later fight with Xavier himself, although Geppei managed to use his formidable onmyou skills to seal the demon, he was not able to do this before being mortally wounded himself.

Still, Geppei wielded the fearsome Death Scythe that would be passed down to become the iconic weapon of the Tenshi Sect head monks. He was also the founder of onmyou arts, and one of the best at sealing as evidenced by his method for sealing Xavier that is even now passed down as a secret technique in the Tenshi Sect.


In LP0005, when the partially-unsealed Xavier took possession of Oda Nobunaga's body, Xavier justified the massacre of Tenshiism followers by declaring it a religion of Devil-worshipers. It is unknown if Xavier actually knew of Geppei's true identity, or if his accusation was just coincidentally on the mark.
