Pokémon: Zhihui Zhihui did not mention this chapter because the novel was not officially published or released, and there was no public plot or plot information. Perhaps the author or editor had not decided or announced the plot yet.
Pokémon Special: Little Blue Natsuya vs. Cora is a novel in the Pokémon series. It appeared in the 58th episode of the Pokémon series,"The Final Battle of Little Blue Natsuya vs. Cora."
Cora could be many things. She might be the protagonist, driving the story forward with her actions and decisions. Or she could be a side character that adds depth to the plot, like a confidante to the main character.
It could be Hermione. In some alternate interpretations, there could be a situation where Hermione, while trying out a new and powerful magic, accidentally hurts Harry. Their friendship is put to the test as Harry has to deal with the pain and Hermione has to come to terms with what she's done.
Faith played a big part too. They believed in God's plan. They trusted that by doing what God asked, they would be safe. This faith gave them the strength and determination to face the difficulties of the flood and the new world after it.
Maybe it's Ron. Suppose Ron gets jealous of Harry's fame and power and, in a moment of weakness and envy, decides to abandon Harry to die. This would create a lot of drama as Ron and Harry have been friends for a long time, and such a betrayal would be a huge shock to the story's readers.
