Tera commands the Musashino Saru gang, championing a non-violent creed and advocating peace among Tokyo's gangs in the wake of the Shibuya riots. His leadership centers on preserving a fragile truce and preventing renewed conflict between the tribes.

His past links directly to Nagisa Hotehama, protagonist of the original "Tokyo Tribe" manga. Tera founded the Musashino Saru as a direct consequence of Nagisa's death, embedding his commitment to pacifism into the gang's core ideology.

Tera's death ignites the Second Gang War. He falls during a clash between Musashino Saru member Kai and Wu-Ronz leader Mera. His demise varies across media: the manga shows decapitation by Mera's sword, while the anime depicts a fatal stabbing leading to blood loss.

His killing fractures the Musashino Saru, driving a wedge between members loyal to his non-violent principles and those demanding vengeance. It also rallies other Tokyo Tribes to unite against the Wu-Ronz and Buppa Clan.

Tera is remembered as Hiroshi Terada, a figure respected across multiple tribes for his moderate stance.
