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 and Cayde coordinate the campaign against the Fallen, providing vital intel to the Guardians on the field.

Biography
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.

Trivia

 * Shiro-4's cloak appears to be made of House Banners belonging to the Fallen House of Kings, and he is wearing Lucky Raspberry.
 * Despite being a student to Cayde-6, Shiro-4 is much more serious in most situations. Shiro only makes a couple of sarcastic quips and remarks during relaxed situations, unlike Cayde who is overtly wise-cracking in nearly all missions.
