Life as a Bodyguard

In the Sengoku era, there was a ninja who took the role as bodyguard of the Feudal Lord for the traitor and greedy samurai that wanted to take the life of that Feudal Lord. Then the day has come that ninja protected the Feudal Lord all of his life and was accidentally killed by samurais. He was reincarnated in the body of a bodyguard who was also killed. This force fused with the body’s dormant power, triggering the Gift. This happened in a world where people have developed Gifts in a modern era.
