characters in remarkably bright creatures

I'm not sure as I haven't read it. Maybe the remarkably bright creatures are the main characters.

No, it isn't. It's a fictional story created by the author's imagination.

It's about remarkable creatures. That's all I really know.

The introduction of the characters in the Strange Creatures Record is as follows: There were many different characters in the book that would have a profound impact on the development of the story. The following are some of the important characters: Xia Qi: Xia Qi was an ordinary college student, but in one of her coincidences, she came into contact with a novel called "The Record of Strange Creatures" and began an unusual life journey. In the novel, Sharkey kept coming into contact with all kinds of strange creatures and gradually grew into a senior abnormal creature hunter. 2 Fang Yuan: Fang Yuan is a mysterious scholar, he has been researching all kinds of mysterious creatures. Not only could he predict the time and place of the appearance of various abnormal creatures, but he could also create various strange biological weapons to support his research work. 3 Amber: Amber is a warrior from an alien planet. She has powerful combat abilities and special abilities. She came to Earth to find her hometown and interact with the creatures on Earth. 4 Raymond: Raymond is a member of a mysterious organization. He is responsible for capturing all kinds of abnormal creatures. He had superb combat skills and special abilities that could easily deal with the attacks of all kinds of abnormal creatures. 5 Lilith: Lilith is a female abnormal creature hunter from Earth. She has unique biological knowledge and rich combat experience. She became good friends with Xia Qi and worked together as an abnormal creature hunter. These are some of the important characters in the book. Each of them has their own unique personality and ability, which has a profound impact on the development of the story.

Most likely Harry Potter himself would be one of the main characters involved in creating creatures. After all, it's in the title. Hermione might also be involved, with her vast knowledge of magic and creatures, she could contribute a great deal to the process.
