Saki came from a distance future to the past. In this past, he have to use his skills to survive. Unfortunately, the time he travelled to is very chaotic. So, in order to survive, he was forced to 'join' a group which turns out to be a group of special forces.
Join Saki as he tried to change the past in hopes that he could avoid the future that he saw. From a normal member, to an important figure, he will win everyone's heart, with his skills, and his 'cheat items' from the future.

Member 3: So this is called cotton candies?
Member 4: Saki, can I borrow your flashlight?
Saki: These ancient people... *shakes head*
