Ryun Seijūrō

"Without question, the strongest force is neither spiritual energy or physical power. It is love. And no, I'm not quoting a cliché drama story. It is a force that can undermine the best of us. In our highest moments, it reveals the weakness in us. The flaws in us. At our lowest points, it shows the true darkness of our hearts. Rivaled by its strength is its danger. Truly... love is a force that even Kidō cannot combat."

- Ryun speaking to Seireitou and Hikaru.

Ryun Seijūrō (清十郎龍神, Seijuurou Ryun) is the former Captain of the Fifth Division in the Gotei 13, having at one time worked alongside Seireitou Kawahiru and Hikaru Kurosaki. He is also the former Yonkō of Kidō, the title that is currently held by Raian Getsueikirite whom is Ryun's direct successor.

Behind the Scenes
Ryun is a homage to the former works of Tenny, whose current work, Raian Getsueikirite, is the culmination of all his years of working on the wiki. Just as Raian succeeded the old Ryun works, that is paralleled here by Raian's succession of the Yonkō title from Ryun.
