Pillars Of The Wu Family

The martial arts family started in its humble beginnings, and its pillars collapsed during the Warring States Period. When the absurd Bushido became popular, who would still remember the original oath of Genji.
When Hashiba Hideyoshi was still worried about finding a godfather and Tokugawa Ieyasu began to call himself Kawachi Genji, they would never understand what the pillar of the Wu family was.
The deep grass in front of Hachiman Palace hides the centuries-old glory of the samurai family. However, the young men of the Kira family are forced to catch up with the times and embark on a path completely different from history.
The bottom conquers the top, and the traitor will only die. All illusions will be reduced to ashes under the rolling iron cavalry, and the Genji family will be reborn under the white flag.
