Edison

Edison is a young Slardian from the Eastern Sea country who attends the theological school Solsein as an international student. In reality, he serves as a cooperative human vessel for the Demon Lord Rathwell, carrying out investigations within the school alongside the demon lord's clone that resides inside him. Under Rathwell's influence, Edison possesses an awakened skill known as "Carbon Formation," enabling him to generate diamond-hard defensive barriers or create light, glider-like structures for transport. When Rathwell utilizes this ability through Edison's body, its physical output is boosted to four hundred percent. Despite his connection to a legendary dark beast and his remarkable potential, Edison is a friendly, calm, and cooperative individual who gets along well with his classmates, often seen walking home with Klen and Sarasa.
