Arash is a heroic spirit from ancient Persian mythology, known as the archer who ended a sixty-year war between Persia and Turan. His arrow flew 2,500 kilometers to establish a new border, an act of sacrifice that shattered his body. This ultimate technique, his Noble Phantasm Stella, is an Anti-Army attack rivaling Anti-Fortress power but ensures his instant death upon activation. In peacetime, Arash is cheerful, righteous, and encouraging, yet in conflict he becomes coldly rational, capable of instantly calculating infinite arrow trajectories. He acts without hesitation, driven to protect the innocent and correct human history. With his Master, he offers loyal companionship while maintaining respectful distance. His skills include Clairvoyance for exceptional sight and future estimation, Robust Health providing endurance and poison immunity—enough to resist Hassan of Serenity’s touch—and the ability to construct bows and mana-forged arrows. Across his appearances, from Camelot to comedic settings, Arash remains a guardian who willingly trades his existence for the greater good, embodying self-sacrifice as a peacemaker.
