Well, it could be that there was a special event at Placido del Mundo Elementary School. Maybe it was a school fair, where students sold handicrafts and food they made. There could also have been some interesting performances by the students, like singing or dancing. Or perhaps it was a sports day, and all the kids were competing in different athletic events.
One possible moral could be about the power of friendship. The witch and the crow might show that different beings can support each other in various situations, no matter how different they are.
Since I don't know the exact story, it could potentially be about a figure who met a watery end and was considered beautiful in a way that defies normal expectations. It could be a story about love and loss, where the person who drowned was remembered in a special way that made them seem the most beautiful. It might also be a story with a moral or lesson, perhaps about the transience of life and the power of memory.
A possible story about Placido del Mundo Elementary School could be that there was a mystery in the school. A valuable item went missing, and a group of clever students decided to play detective to find out who took it. They interviewed teachers and students, searched every corner of the school, and finally found that it was just a misunderstanding. The item was accidentally moved by the janitor while cleaning.
The main characters are surely the bruja (witch) and the crow. The bruja might be depicted as having certain powers or characteristics typical of witches in folklore, such as being able to cast spells or having a connection with the supernatural. The crow, on the other hand, could play different roles. It could be a messenger for the bruja, or it could be a creature that the bruja is trying to either help or control. There could also be a relationship where the crow is the only friend of the bruja in a world that might be otherwise hostile to her.
