Stella is a girl who transferred from her original knight department to run a mission to recruit two girls and two boys to her department. However, there is quite the hassle to get back to Stella's precinct. Upon returning, Stella and the new recruits are told that the world is in danger, and of course this means they have to go save it from total destruction. Strange occurances on the trip end up making them a confusing family. The boys try to lighten the mood with jokes, while the girls chase the truth. They all scramble to finish the puzzle, but the last pieces are secrets that each of them is keeping from the others...
The story of these five becoming a trusting family is one of hardships, reliving your worst memories, and tragic events. However, without each other, their quest will fail. The bad news is that the enemy knows more than the heroes, and while the group takes a cross-country tour, the enemy plots. And they plot not with brain or brawn, but with the overwhelming power of human emotion.
