Reach had become the grave of many Spartans after its Fall in 2552. Surprisingly, two close brothers who were among Beta Company's survivors and its most elite were 'spared' their deaths and given a new lease of life, in another universe and in another, more peaceful time. However, their calm lives turn wild as they befriend a Yakuza boy with a Childhood Promise and an old locket.

The Master Chief sacrificed himself to save humanity from Didact but at what cost, he lost his companion, his good friend companion, Cortana. He thought that he was dead until by some unknown force, he was sent back to the past. There the Spartan awakens to a different 21st Century Earth. How would his presence affect everyone? What will the Spartan do?

Now working for this planeswalker, Noble Six will travel to different fandoms/planes to accomplish objectives for this eccentric god-like being... In this first installment, Noble Six travels to world of Nisekoi. This is not a Crack story.
