Randomly changing the plot, privately setting up Tsunade to find out that she was pregnant with a posthumous child after Kato Dan, and she gave birth to a child. After the Third Ninja War, she left Konoha with her 11-year-old son and Shizune.
Kato Akira has not seen his father since he was a child, and his mother went to the battlefield again. He only has a Shizune sister to take care of him. He was also prevented from entering the ninja school by his mother because he did not want Kato Akira to die on the battlefield. Because he could not learn ninjutsu, Kato Akira studied the medical ninjutsu scrolls left by Tsunade at home.
Kato Kyung blamed Tsunade's words. He knew that his mother's choice was all for himself. She just wanted her son to live.
11-Year-old Kato Akira was taken away from Konoha by Tsunade, and he learned medical ninjutsu at a deeper level by his side. While studying, he made money for his mother to pay for food. After all, her mother lost nine out of ten bets and was a big fat sheep in the casino.
But everything stopped when Kato Akira was 15 years old. He was silenced for discovering a shocking secret while collecting medicine. Little did he know that this time it was reported to Tsunade by the psychic beast Slug. Kato Akira's death made Tsunade furious. She wanted everyone involved in the murder of her son to pay the price.
Tsunade returned to Konoha with the body of Akira Kato and the sad Shizune, and smashed the headquarters unstoppably, beating Danzo to the point of being paralyzed. She also drove the old, soft-hearted and pedantic Hiruzen Sarutobi out of office, brought the old pervert Jiraiya back as the Fifth Hokage, arranged for Akira Kato to be buried next to the grave of Kato Dan of the Senju clan, and then pursued Orochimaru.
Kato Akira didn't know that his mother had done so many things for him, because he woke up and came to a strange place, and was told by a strange thing that it wanted to eat him. Kato Akira naturally fought back, wrapping his hands with chakra and beating him with strange power. The offended ghost who said he was the supreme ghost and Kato Akira was food. Of course, the offended Kato Akira would not let go of the ghost who treated him as a dish. He beat him up for half an hour and finally let Kato Akira use a chakra scalpel to understand the ghost.
Intention: I just want to go home!
