Yasuki Heike

Yasuki Heike was born in the Crane Clan, and in the years after the First Yasuki War he was fostered into the Daidoji, but he kept his original family name. His twin brother Yasuki Taira joined the Crab and was given command of the coastal village of Dannoura.

Death
No one was certain what prompted the Battle of Dannoura between brothers, but the result was the death of both along with hundreds of their men, while Dannoura burned to the ground.

Aftermath
After that battle start appeared heikegani, the so-called “Samurai Crab”. It was a unique species of crab, with a shell that bore a pattern resembling the face of an angry samurai. The superstitious believed these crabs were reincarnated souls from Toshigoku, the Realm of Slaughter, and it was considered unlucky to eat the plentiful heikegani from the region, for to do so was to invite the sin of familial betrayal into one's heart.
