Ryuzetsu

How Ryuzetsu joined the Tourney
Ryūzetsu belonged to the Grass Fruit Group of Kusagakure and was childhood friends with Mui's son, Muku. As children, they both dreamed of resurrecting the glory of Kusagakure. Eventually, she witnessed Mui sacrificing Muku in a failed attempt to open the Box of Ultimate Bliss, leaving only his green scarf. She is seen wearing this same scarf as a bandanna during her trek into Mui's Hōzuki Castle in order to not only stop him from re-opening the Box of Ultimate Bliss, but to avenge Muku's death.

With the second Tourney underway, Ryuzetsu is ordered to track down Obadiah Stane who's seeking to use the Box of Ultimate Bliss for war profits. She soon learns he has become Iron Monger.
