An orphan who shares a friendly rivalry with
Reiji dating back to their time in the same orphanage. He has witnessed incessant war and suffering during travels with his foster father and now bears a deep hatred for "evil".
Ryuuichi is as dense as he is stubborn for justice, reflecting any female affections like a wall.
In battle, his hair becomes blond and his eyes turn green due to him infusing the power of lightning with himself. He is able to move in the speed of light and can deal lightning-based attacks.
