   Summary

   16-year-old Kagami makes one mistake while studying the Hiraishin—and wakes up in the body of his 4-year-old self.

   Determined to save his brother from the fate he remembers, Kagami changes history... and accidentally leaves Izuna gravely injured. Trapped in a deadly snowstorm with no supplies and shelter days away, Kagami senses a familiar chakra nearby: his future sensei.

   If anyone can save Izuna, it's the Senju hidden in the cave ahead.

   And since Kagami already knows—purely by accident, of course—that Izuna-sama is hopelessly in love with him, he might as well play matchmaker while he's busy rewriting history.
