Heichi grew up in the heart of the small Boar Clan. The Boar are a minor clan, that is famous for their weapon craftsmanship, but with little influence or power in Rokugan. Takagi himself is the epitome of the Boar Bushi wielding his Mai Chong with deadly power.
Heichi was working as a yojimbo for a Boar Courtier at the Crab lands when they heard the news of the Emerald Champion was marching against the Boar, Takagi's rage and fury were great but not enough to escape the Crab lands after such “generous offer” by their host to remain until everything was settled. Not long after news came of the Boar Clan being destroyed with Emerald Magistrate “advising” Takagi and the other Boar Clan survivor to not claim their heritage, the Crab took them in as one of their one but Takagi refused to relinquish the Heichi name but remained in the Crab lands defending the Kaiu Wall to die with honor and as a Boar Bushi. Takagi eventually found his death in one of the many skirmishes with the shadowlands and now his spirit was sent to Yomi as with all his Blessed Ancestors.
Peace in Yomi was disturbed when an Emperor Toturi asked for help against the Shadow that was threatening to consume Rokugan. All the spirits as well as Takagi agreed that they will once again draw their swords to fight the real and only enemy of Rokugan. Takagi marched with great heroes and ancestors towards Oblivion Gate that opened for them to join the battle where everyone fought desperately to destroy the Shadow. Takagi fought to the best of his ability with creatures of the shadowlands but by the time he reached the actual battle in the inner city it was all over. In the aftermath of the war Takagi was left with no place to go as the Boar Clan was no more.
Takagi now travels Rokugan as a ronin concealing his true identity for the trouble it might cause him, until the time is right to reveal himself as the last Heichi and inheritor of the Boar Clan.
