You Were Supposed to Be Hokage, So Why Have Your Subordinates Gone Beyond the Universe?

System + Making Up for Past Regrets + Multiple Heroines + Beyond the Shinobi World

A modern soul merges with Shisui's memories, becoming a new Shisui and awakening a System.

Everything in the Shinobi World changes as a result.

The Uchiha clan will not be wiped out, and Naruto and Sasuke will no longer have miserable childhoods.

Karin's mother will live, and Jugo will no longer need to be kept in a "cage."

Kimimaro will never meet Orochimaru, and Yakushi Kabuto will not kill the orphanage director who raised him.

Everything will become better, and the Shinobi World will no longer be filled with sorrow.
