Shion (士遠), previously known as Yamada Asaemon Shion (山田やま浅だあェえも門ん 士遠), is the former 4th rank Asaemon of the Yamada clan. He is a major supporting character of Hell's Paradise: Jigokuraku.

After the shogun called for death row convicts to acquire the Elixir of Life from the dangerous island believed to be Shinsenkyō, in exchange for a pardon for their past crimes, Shion joined in the expedition team as one of the Yamada Asaemon monitors and was assigned to keep watch over the criminal Akaginu.
