Fate/kaleid liner Prisma☆Illya: Vow in the Snow

After a grim fate takes Kiritsugu Emiya, his adopted son Shirou inherits the burden of saving humanity. The world is crumbling, and time is running out-but when the only path to salvation demands sacrificing his little sister, the last family he has left, can Shirou bring himself to follow through? Now he faces a cruel choice: cling to his dream of being a hero of justice or embrace the evil he once swore to destroy. Alone once more, Shirou remains a vessel of blades, his body forged from swords. As the Fifth Holy Grail War unfolds, his fate is sealed beneath the falling snow.
