Hayato Fūrinji/History

==Background==
Not much is known about Hayato's past but it has been shown in flashbacks that he took on 500 martial artists at once. He also at some point had a son, Saiga, who sired his granddaughter Miu, whom he gained custody over after the death of her mother. He arrived too late too see what had happened, but found his daughter-in-law dead and his granddaughter hidden in the snow. During WWII he worked with Mikumo Kushinada to stop and defeat many Yami bases.
It has also been shown that Hayato used to travel the world with Miu and help out people in need where he would also instruct her in martial arts, around the time of which he met Apachai. When he met Apachai, he fought him on a cruise ship due to the latter being tricked into thinking he was helping the victims. Miu was also on the ship and held as hostage, greatly angering Hayato. After telling Apachai of the meaning of the children held hostage, Apachai turned sides and assisted Hayato in saving them and his granddaughter. Afterwards, Apachai choose to follow Hayato and the former brought him to Ryozanpaku due to seeing good in the man.
At some point, Hayato became acquainted with Silkwat Junazard, a member of Yami. For a time, they were friends and Junazard taught Hayato much of his land's medical techniques. Later, Junazard and Hayato would end up fighting each other, with Hayato stating that Junazard gave him a hard time. Before a clear winner could be determined, the battle was called off by the Elder who was forced to leave due to his boat fixing to leave soon.
He became acquainted with the master of the Tenchi Mushin Ryuu schools master Kai Midou, having been aware of Ogata's experimentation he did on him, leaving him with bad health. He was also responsible for meeting his lone disciple, Tsutomu Tanaka and helping him marrying his only daughter Mayu Tanaka. However, the elder was unable to see that Ogata would later take not just Midou's life, but also Mayu's and her unborn childs life, leaving Tanaka a broken man, to which the elder would be the only one with the knowledge of the incident.
