Coral Island: Strange Girl

This is my first work, original, at the level of middle school students. All the characters are my own ideas. The story is preceded by a long day-to-day life in the academy. It is a story about saving the world, as follows: The protagonist group lives on an island called Coral Island, located in the middle of the Pacific Ocean. There are various races living on the island, such as humans, elves, hidden dragons and a few saints. Each race has its own territory, such as the human city, the elf capital, and the Warring States Period. Humans may awaken supernatural powers during puberty at the age of 10. People who awaken their powers will go to specialized schools to study and control their powers to defeat evil forces.
