Aikawa is one of Ai's several alter-egos. He's an easy going guy who loves good food and always stands up for his friends. However, because he shares a body with the psychopathic Kai, another one of Ai's alter-egos, anyone Aikawa gets close to tends to meet an untimely death. This is because anything Aikawa overhears Kai learns too. Even Aikawa's best friend, Risu, fell victim to Kai after he told Aikawa of his newly-discovered magical abilities. Aikawa hates Kai and ties to sabotage him any way he can, even attempting to kill himself to take Kai down with him. Alas, their body isn't that easy to destroy.
