Voiced by: Arata Iura
In a city where the streets are crowded with restaurants and nightlife establishments, Tetsu Tachibana has earned a reputation as the real estate mogul in the shadows for his skill in buying up land as soon as it hits the market. He will take any means necessary to obtain that which is in his sights. Despite his soft-spoken and sophisticated demeanor, Tachibana's ambitions are great. He aims to challenge Tojo Clan itself in his aim to take power over Kamurocho. Along side with his sworn brother,Jun Oda and his friend,Kiryu Kazuma,they aim to take the Empty Lot as Kazama's request.Tachibana was then alarmed that The Dojima Family was after him so he hid. Tachibana then meet with Kiryu in the Empty Lot and telling him he will find the owner.But first,he had get Dojima Family off of Kiryu so he and Oda and Kiryu met with the Acting Second Chairmen of the Tojo Clan,Takashi Nihara to persuade to get Dojima off of Kiryu,Nihara had been persuaded.Tachibana then met with Kiryu in Little Asia and told the owner of the Empty Lot,It was Makoto Makimura,a blind girl who was a target of Omi Alliance and Shimano Family. Tachibana was in his wounds and Kiryu then went to know about Makoto.Oda told him that Makoto Makimura(Xiao Qiao) was Tachibana's sister.They were both born in China and was separated.When Tachibana told Kiryu it was true Kiryu told him that Oda tried to kill Makoto.He told him that Oda was"The Man With The Bat"who sold Makoto,and told him that Oda was killed by Dojima lieutenant,Shibusawa.After that,Tachibana crys and wants to see Xiao Qiao.However was taken by Dojima Assassin,Lao Gui and beings tortured by Dojima lieutenant,Daisaku Kuze. Tachibana was killed by a sledgehammer by Younda.
Born to a Chinese father and Japanese mother, Tetsu's life was one born of discrimination and strife as in his youth he and Xiao Qiao would endure humiliation and insults from their peers for being half blooded in China. Feeling that there is no place for him in the country, he left early in his youth. Fleeing to Japan to make a new life for himself, unable to find meaningful work, he resorts to crime and quickly became a ruthless criminal with little regard for the morality of others. Soon after he meets Jun Oda, the leader of a small gang after beating him in a fight and they worked together as partners in crime. However learning that his sister is alive he turns to Shintaro Kazama for help, through him he formed Tachibana Real Estate.
Yakuza 0 Edit
Upon learning that Kazama's position is threatened and Kiryu has been exiled from the Yakuza, he was sent to find the distraught man and make him an offer as a real estate agent for Tachibana Estates. Here he reveals that he plans on challenging the Dojima by obtaining the land first before they do. Entrusting his old partner in crime Jun Oda, he eventually discovers the location of the owner of the Empty Lot. After Kiryu's seemingly last stand against Kuze, Tachibana arrives and saves Kiryu and hatches a plan where he offers a cut of their company's income in exchange for Kiryu receiving amnesty until the land is found.
After Kiryu and Makoto returns to Kamurocho, Tachibana reveals his past and the possible fate of the Tojo clan if they do not acquire the land for Kazama. Before they could make their move they are cornered by the Dojima who sends their assassin to eliminate Kiryu. With no options left, Tachibana lets himself be taken into Dojima's custody where they tortured him. Defiantly opposing them even in torture, Yoneda lands a fatal blow that leaves Tachibana lethally wounded. In his dying words he reveals that Sohei was responsible for everything to Kiryu and Nishikiyama and succumb to his fatal wounds
Tachibana displays a cool demeanor, and is a seemingly calm and emotionless man. These main characteristics helps him serve as a counterpart to the more fiery Jun. Tetsu in his youth suffered discrimination from others and thus became fearful of others. Moving to Japan, he quickly turned that fear into anger and brutality as he turns to a life of crime and became ruthless. Only learning that his sister has come to Japan and was still alive did he regain some resemblance of conscience. When he finally learns that Makoto is alive he felt remorseful for the man he had become to survive in the Japanese underworld.
