Jian is the Kusagari swordsmaster. He was saved from getting killed by the Jackals by the Unnamed Protagonist.
In Red Steel 2Edit
When you first find Jian, he lets you borrow his katana until you get your katana back. Also, at Jian's shop, you can buy hidden strikes and katana upgrades. Occasionally, (usually when you win a boss battle,) Jian will teach you a Kusagari power, the first of which is the Eagle.
