He is wrapped in blue flames and inherits the power of the devil
He hates all demons and vows to kill them all under his own gun
He has everyone's memories etched in his memory but buries them deep in his heart just to protect them.
He was wiped away from all memories of that person, leaving only his father's hatred
He is Rin Okumura
He is Yukio Okumura
They are twins linked by fate
