Reincarnated with Whitebeards power

A 27 year old retired American Soldier saves a school of small orphaned children from a group of gangsters that threatened the school and bring it down. He had survived but died with the increasing number of gangsters that came by to help. He at least died knowing he protected a group of innocent children from something horrible. Luckily for him a group of officers were nearby and heard the commotion and called for back up. Although he did not survive he knew he accomplished something incredible in his bloody life. When thinking that was it, he thought what would happen next. But he never expected seeing someone from his childhood be real and especially about giving him his Legacy. This is the beginning of a man who would be known throughout the multiverse as a father figure and worst person to come across. NOTICE: Any type of work or images I show are not mine and in no way am I that good at drawing or art. Animes, Shows, novels, manga I get my character go through are not mine but their respective authors so give them credit for their amazing work. Notice 2: Whenever there are fights the chapters will be longer but because I want to make it exiting and it makes development to the story.
