Those who have quirks have come all corners of the world to become heroes and to train their quirks. Though on one day a soldier from another life who was taken and became one of the UNSC'S greatest soldiers a Spartan II super soldier with a AI who try to go home but now are stuck until another way was found.

Only his duty as a Spartan to protect humanity no matter the cost.
