Crossing Swords! Roger and Whitebeard!

Orochi became Oden's proxy as he was at sea, but the other daimyos suspect him because he was a member of the Kurozumi Family. It is revealed that before Sukiyaki was born Orochi's grandfather had attempted to take over by assassinating the other daimyos. When assassination plot was exposed, Orochi's grandfather was forced to commit seppuku, and the people grew to despise the Kurozumi name to the point lynch mobs were formed to hunt down any members. While hiding from the mobs one day, Orochi met his distant relatives Semimaru and Higurashi, the latter being a former user of the Clone-Clone Fruit. After being told of his family history and being given Snake-Snake Fruit, Model: Yamata no Orochi, Orochi plots to take the shogunate with Higurashi's assistance. Orochi needed to collect funding to buy weapons, so he stole money from Yasuie while working undercover as a servant and asked Oden for loans without paying him back. Higurashi then disguised herself as Oden to convince the shogun to let Orochi into the palace, where he became the shogun's faithful servant. Years later, Higurashi disguised herself as Sukiyaki, pretended to fall ill and spread news that Sukiyaki died of the illness, allowing Orochi to rise to power. Overseas, Oden on his fourth year under the Whitebeard Pirates, along with Toki had another child, their daughter Hiyori. One day, the Whitebeard Pirates approach an island being plundered the Roger Pirates. Oden charges in to face them, but Roger sends the samurai flying though several trees with a single swing of his sword. Oden quickly recovers and tries to return to Roger, but Whitebeard then comes and engages in a monstrous clash with the pirate, the force of their power so great, it blows back everything on the island without their blades even touching.
