Akira

Akira is a black haired boy who looks very much like Souchiro (Teru's older brother). He is around Teru's age, has slanted eyes, and is about 170 centimeters tall. His build is lithe, like a cat's. He also carries around a yo-yo. He also has extraordinary arithmetic skills and he has the ability to decipher a complex code just by simply looking at it.
