Zakuro Oshigiri, a 16-year-old male with a slender frame and pale blond hair, stands at 166 cm, his striking purple eyes contrasting against the black mask obscuring scars along his jawline—a lasting mark from his twin sister Sakura’s accidental slip of scissors. His attire blends practicality and subtle flair: a black V-neck shirt tucked into low-hip jeans secured by a belt, layered under a crisp white jacket adorned with black sleeve stripes and a collar that arches high against his neck. Black boots, laced with intricate designs, accompany white socks, while twin black rings glint on his left index and middle fingers.

A stealth-focused game uploader, Zakuro masters the art of invisibility, both online and in reality. His demeanor leans rigidly serious, a stoic front masking a shyness that flares around women—blushing fiercely, recoiling at proximity—a reflex honed by years at an all-boys school. This inexperience fuels naive assumptions, like girls concealing poison for protection. Yet beneath the reserve lies a fiercely loyal guardian, vigilantly shielding friends and family.

Two years prior, Sakura vanished after entering a mysterious game, her absence haunting Zakuro despite exhaustive searches. Driven by unresolved guilt over the scar she inadvertently gave him and desperate to trace her fate, he plunged into the same digital labyrinth, determined to breach the world that swallowed her.

Interactions expose Zakuro’s contrasts: gentle protectiveness toward Makino and Sakura, brusqueness with most boys save select allies, and skittish unease around girls, dodging touch unless deeming them harmless. Quick to trust absurd claims—like the poison myth—his temper ignites when Sakura’s name is taunted. Yet through every flaw, his core remains unshaken—a watchful sentinel, prioritizing those he cherishes above all.
