In the world of Alternative, there exists a different side of the war against the BETA.

There exists a woman, Himiko, with the power to predict the future, to see the timeflow of every possibility, and to pick the best option available at any given time. According to tradition, her power has always been used to avert disaster, allowing the common people to prosper.

Surrounding this person are the Sakimori, a group of superpowered warriors. Exceptionally skilled fighters both in and out of a TSF, who can take on lesser BETA strains on foot, they protect their leader from the shadows. Armed with never-before-seen power and machines, they keep Japan safe, stepping into dangers no sane person would willingly face.

This is an epic of bravery, of burning justice.

This is Ayu-Mayu Alternative.
