Shiro-4

"Whatever you do, don't call the wolves "mascots" while Saladin is around."

- Shiro-4

Shiro-4 is an Exo Guardian who resides at the Iron Temple. Apart from being a trusted ally of Cayde-6, he also runs scouting missions for the Vanguard. During the SIVA Crisis Shiro-4 helped Lord Saladin Forge and Cayde coordinate the campaign against the Fallen, providing vital intel to the Guardians on the field. Before he became a Vanguard scout, Shiro-4 was part of a Fireteam made up of the deceased Hunter Vanguard Andal Brask and Cayde-6. He was partnered with the Ghost Suzume.

Biography
"There's a stone cairn outside the city; been there since Six Fronts. No one visits it, but once a year, I put a fresh lily on top. I hope it brings them peace."

- Shiro-4

Shiro-4 participated in fighting back a Fallen assault on The Last City known as Six Fronts. In the aftermath of the battle, a stone cairn was built to commemorate the dead just outside of the City. Shiro would visit the memorial every year and place a lily on top in remembrance of his fellow Guardians who perished in the battle.

Shiro-4 long served as a protégé to Cayde-6 before the latter's rise to the Vanguard post and was believed to have wielded the Trespasser Exotic sidearm. Free of the burden of leadership that ties his mentor to the Tower, Shiro willingly aids the Vanguard whenever his skills are requested. Tasked with tracking and eliminating Fallen threats, Shiro has traditionally spent most of his time making runs between Earth, Luna and Venus—gathering intel and engaging in hit-and-run attacks on active Fallen crews. Shiro's selflessness—combined with his talents for tracking, weapons-crafting, and combat—makes Shiro an invaluable extension of the Vanguard's will beyond the City.

When the House of Devils returned and rediscovered the nano-tech plague, SIVA, utilizing it to evolve themselves and corrupt the Plaguelands, Shiro worked alongside Lord Saladin to combat the mutated Fallen. Shiro assigned patrols and strikes against the Devil Splicers, such as destroying Sepiks Perfected, ending the Splicers' experiments on the Hive by killing Kovik, Splicer Priest and finally slaying the Splicer leader, Aksis, Archon Prime.

Shiro also played a role in deciphering the puzzle in the SIVA server farm that led to the creation of the Exotic Pulse Rifle, Outbreak Prime.

A year after the Red War, Cayde-6 dies in the hands of Uldren Sov. At some point during/after Cayde-6's funeral, Shiro-4's Ghost Suzume recounts the first time Cayde and his Ghost, Sundance, had met and started their friendship.

Personality and traits
"You are not welcome." "I beg to differ."

- An Unknown Enemy and Shiro-4

Unlike his mentor Cayde-6, Shiro is much more no-nonsense and wastes little time joking around outside of occasional sarcasm. He also relies heavily on intel, while Cayde is known for his precise intuition. Though he respected the more experienced Guardians like Lord Saladin and would defer to their leadership, he was not completely subservient as he voiced the opinion that the House of Devils Fallen were the more immediate threat than SIVA, which turned out to be true when the Devil Splicers revealed themselves.

Though Shiro respected his mentor and mourned his death greatly, he joined the majority of Hunters in stating that he absolutely has no interest in taking Cayde's place in becoming the next Hunter Vanguard, though his Ghost believed he should.

Trivia
