Sansei Muramasa stands in a commanding, action-ready pose rendered in a faithful 1/7 scale Oasis ver. at approximately 230 mm tall. He wears ornate lacquered armor with layered plates, embossed motifs, and subtle weathering that hints at long campaigns. Teal edge highlights trace the curves of the armor, while a flowing cloak adds motion as if caught in a gust. His long hair cascades behind him in a pale ash hue, and his expression remains calm, focused, and ready to strike. The katana is drawn halfway, catching light along a razor-thin edge, with a guard that glints like ice. The base features rippling water and subtle spray, echoing the Oasis theme and giving a sense of immersion in a battlefield of wind and water.

In the world of Soukou Akki Muramasa, Sansei Muramasa is the third generation bearer of a legend-touched blade whose power awakens when the realm faces its darkest peril. Trained from a young age to temper instinct with discipline, he moves through the story as a measured swordsman who tests the blade’s edge against rival clans, imprisoned spirits, and corrupt ambitions. The Muramasa lineage is bound by a pact that requires sacrifice as the price of great skill, forcing Sansei to choose between personal longing and the greater good. His journey interweaves loyalty to comrades and a solitary burden, a quest to redeem past missteps while safeguarding towns and travelers from marauding forces. The Oasis variant emphasizes his resilience and resolve, presenting a figure forged by storm and sea, steady amid chaos.
