Isawa Ryuiso

Ryuiso was an Elemental Master, though his element is not recorded. He was Master during the Battle of Sleeping River, and was instrumental in the Phoenix Clan's attempts to negotiate a truce with Iuchiban. During these negotiations, the Phoenix offered to ally with the Bloodspeakers if they would accept a reasonable compromise and if Iuchiban would abandon his quest to become emperor.

Ryuiso is the example that other clans use to discredit Phoenix pacifism, saying that they will sacrifice even honor and tradition if it will bring peace. (Phoenix p. 25)
