Death Secretly Loves Life

The world has been practically turned into a videogame, except you don't choose your class, race, and abilities. Sasuke Uchiha is born a necromancer with the power to control the living and the dead, basically able to control armies, and death isn't even an option of escape. Naruto Uzumaki is born as a healer, even able to resurrect the dead, and interrupt any spells that may hurt his allies, as well as the usual healer abilities. Complete opposites, but the two end up on the same team in the game of life, and are stuck with each other until this level is completed.
