Natsume and the Monsters

What would happen if an illegal traveler named Mary Sue appeared in Natsume's world? World Line: The old Natsume mentioned in The Long Road Home in Season 3 Background: ① Natsume: Because of Mary Sue's intervention, Natsume suffered more serious bullying when she was a child and did not survive the arrival of the Fujiwara couple. She was relatively silent and had no good impression of humans. Then she was framed by Mary Sue due to malnutrition and died in battle. Later, because the demon power was too strong, she turned into a demon and returned to Yahara's home (you know, Natsume's real home is in Yahara) and lived a normal life. ?②Matsume and others: Because Natsume was killed in battle, Mary Sue wanted to attack Nishimura and others. They went to Natsume High School. But by chance, she changed the world line too much and was punished by God. Miyaguchi and others restored their memories. When they saw Marisu, they were very angry and put her under house arrest (they believed that Natsume didn't want them to do something too cruel) to look for Natsume. Intention: None
