Because Aoshi had becomed possessed, Okina had tried to change him back. Aoshi met the old Oniwa Banshu member at "Location A" when he was invited to the shrine up in the moutains. With finding the location of Kenshin on his mind, both men sprung into battle. The Okina was quick for his old age, attacking Aoshi with his two tonfas. Yet, Aoshi blocked every one of his moves. Soon, Aoshi disappeared, moving around Okina like flowing water. When he had come out of the Ryuusi no Ugoki, Okina had blocked his surprise attack. Yet, Aoshi managed to cut one Okina's tonfas with his Onmyou Kousa technique.

Still, Aoshi demanded to know the location of Kenshin, but determined as he was, Okina refused to let out anything. Aoshi had tried to stab the Okina. To his surprise, Okina hit him hard with one of his signature techniques, the Ensatsu Gokoukon. Okina began to feel the battle was shifting over to his side, but his move barely hurt Aoshi. With his kodachis upside-down, Aoshi slashed six times, hitting Okina with the Kaiten Kenbu Rokuren. It wasn't until a few seconds later that Okina fell down to the ground in a pool of his own blood.
