Yuri, once known as Hasebe Yuika, was a Heishin High student killed in an explosion before reincarnating into a fantasy realm. Abandoned as an infant, the Church of Ullen in the Holy Kingdom of Alleius molded her into a fervent devotee of the Word of God. Isolated upbringing twisted her worldview, breeding fanaticism and intolerance—dissenters faced ruthless judgment, often execution.

Her past self contrasted starkly: empathetic and principled, she once shielded classmate Natsume from peers’ scorn. Reborn, she obsessively proselytizes, clashing with Schlain “Shun” Zagan Analeit, a reincarnated prince and former classmate. Their bond fractures under her relentless zeal.

At the royal academy, Yuri’s interactions with Shun, Sue, and Katia revolve around her religious fervor. After Shun departs, she halts her evangelism abruptly. This shift stems from Hugo Baint von Renxadt, a peer who hijacks the Word of God faith to crown himself a false Hero. Brainwashed by Hugo’s schemes, Yuri ascends as the church’s Saint—a hollow title enmeshed in political deceit.

Her powers reflect her ordained role: *Dreaming Maiden* spawns subspace dungeons shaped by her unconscious mind, while *Lightning Magic* commands storms and sparks. Both skills, honed since childhood, mark her as the Hero’s destined supporter.

Visually, Yuri’s rebirth transformed hazel eyes and a chin-length bob into emerald-green irises and waist-length ashen hair, typically braided. She dons her academy uniform or verdant saintly robes. Her journey—from isolated orphan to Hugo’s pawn—mirrors the fantasy world’s themes of indoctrination, power corruption, and identity erosion under systemic manipulation.
