Introduction

In a time where numbers define who you are as a unit, 10 teens with seperate numbers are set out on a mission to find "Number 0", a legendary group who is said to be in the Mountains of Zarics.

However, forming friendships is hard as these 10 teenagers are different number groups. They were taught as children to not associate themselves with people of different numbers.

Will they complete the mission and return to their families or die trying?
