Manta's Black-Haired Classmate

Once upon a time, there was a middle school student named Manta who had a black-haired classmate. This classmate was a bit of a troublemaker, but he was also very kind and loyal to his friends. He was always there for Manta when he needed him, and they would often go on adventures together. One day, they were exploring the woods when they came across a strange creature. The creature was a shaman, and he told them that they were destined to be shamans themselves. Manta and his classmate were shocked, but they were also excited to learn more about this new world. They began to train with the shaman, and they soon learned how to use their powers. They used their powers to help people, and they also fought against evil spirits. They had many adventures together, and they became the best of friends.
