Biography
Osaka, Japan
On 1 October 2013, while sailing on the Sulu Sea, Barraza inspected the weapons the crew had bought from Philippine gun makers, in preparation for a possible fight with Abstergo agents in Osaka, Japan.
Emmanuel and his fellow Assassins arrived in Osaka on 4 December, and he accompanied Assassin leader Gavin Banks and another Assassin to the headquarters of the Osaka Brotherhood. They discovered their fellow Assassins had been wiped out, and Emmanuel used his expertise to determine where bodies fell and how they died. Gavin used his Eagle Vision to discover the Yakuza, not Abstergo, were behind the attack. Emmanuel and his fellow Assassins were then ordered to locate any Assassin survivors or the identity of the attackers.
A supposedly extinct branch of the Yakuza called the Onmoraki-Gumi came under suspicion as the perpetrators of the attack, and on 12 December, Emmanuel managed to trail a cash deposit to the Onmoraki's new headquarters.
