Shi-Tau, a genetically engineered mecha pilot serving the antagonistic Hau Dragon organization, commands the Gallowin of Water—a combat-specialized unit among the eight Hakkeshu mechas. As the twin sister of Shi-Aen, her impatient and hot-headed disposition frequently drives rash battlefield choices, contrasting sharply with her sibling’s composure and marking a critical tactical vulnerability. Tasked with reclaiming the stolen Zeorymer unit, she clashes relentlessly with opposing forces. Preferring close-quarters combat, Shi-Tau wields a whip as her signature weapon. Her engineered origins reflect Hau Dragon’s strategic dependence on genetically enhanced operatives for their military endeavors.
