A prequel story set seven years before the beginning of the Re:ZERO series. Emilia lives in a secluded forest covered in snow with the spirit Puck. The forest holds a secret: the elves who once lived there have been frozen into ice. Emilia is feared by the people living on the outskirts of the forest, but makes a humble living selling magic stones and warding off Magic Beasts. One day, however, her peaceful life is disrupted when the Great Spirit of Fire Melakuera decides to lay his judgment upon her.

The three brothers discover that the human experiment banned after destroying the "Orochi", is still going on to secretly revive the evil snake. They also find out that some ex-members of the Yamainu (the Japanese military unit formed to kill the snake) are behind this conspiracy. The brothers fight together again in a battle against the military.

Although traumatized by witnessing the murder of his parents by one of the Choushuu, Ichimura Tetsunosuke's thirst for revenge leads him to desire strength. At the age of 15, Tetsunosuke approached the Shinsengumi, wanting to become one of its members. However, Tetsunosuke lacked the skill, mind, and will to emotionlessly cut down whoever threatened peace and the Shinsengumi. Even with the support of his brother Tatsunosuke and his newfound friends of the Shinsengumi, little did Tetsunosuke know the blood and pain he would have to face being part of this historical group.
