Known as "Dragon" Asaga, he grew up a short frail young boy, but after working hard with his childhood friends he became a strong and kind hearted man. He is now one of the fighters in the Psyren games with the power to create a dragon out of his psychic powers.
Hiryu is a rather serious and brooding high school student with a kind heart and strong sense of duty. He is also well known for his good fighting skills and is often targeted by local punks.
His Burst is creating energy constructs shaped like a dragon's body parts. He can create a dragon's tail to hit an opponent or constrict them. He can also create a dragon's wings. He could originally only make one wing and create gusts but after some time he could create two. He was even able to make an entire body and use it to fly with multiple passengers.
Hiryu's purpose for becoming a Psyren drifter was not fame, fortune, or to discover the mystery but to find his best friend, Tatsuo who became a drifter before him. Because of this, after he got separated and found Tatsuo, he stayed with his friend instead of joining up with Ageha and the rest of Tenjuu's root. But because of this, he was able to help Tatsuo and his friend complete their plan to kill many tavoo as well as inhibit W.I.S.E.
