Yuki—white-haired, gray-eyed, calm as a blade—gets dragged into the shogun’s gamble: Kotaku island, Elixir of Life, pardon if she survives, she walks into hell like it’s a stroll. Iron fans snap, wind cuts, bodies drop. No drama. No mercy. Just her, the island, and whatever’s waiting. (Graphic violence, canon-typical gore, female OC, slow-burn tension, Tessenjutsu combat.)
