Tsunami continues to tell Billy that Su Lien is the greatest of all chi masters and wants to meet her which Billy agreed. As he continued practicing martial arts, Tsunami's story about his mentor Sui Lien was overheard by Sickle who is hiding in the sewers and to inform the Shadow Master about what he had heard.

At Mid-Town Dojo, it was revealed that Tsunami is a teacher to his own students who practicing chi and his mentor Su Lien who served as his guests and Su Lien decided to teach them how to use chi until Billy and his brother Jimmy Lee arrive in late to interrupt their practice session which Billy introduces himself and his brother Jimmy and he humbly apologizes and wants to attend her chi class which Su Lien accepts them and both brothers sit while Tsunami is behind them.

Billy tells her that he thinks of the Shadow Warriors are attacking her and it was a mistake. Because of the damage happened on their dojo, Su Lien states that they caused violence and her class is finally over.

They take action by transforming to their Dragon Warrior forms and to confront them.

Despite their transformed appearance and defeating the Shadow Warriors, Su Lien recognizes Billy's real identity and Billy knows who he was. He tried to reason to her about the Shadow Master's trick into going to him but she refused stating that she needs his help. With no other choice, Su Lien decided to go to the Shadow Master and despite Jimmy tells Tsunami of how bad they were, he follows his mentor and tells him to release Sickle on a garbage can which he did.

The mercenaries manage to ensnare Tsunami with their ropes causing the latter to escape by ramming into the wall. The Shadow Warriors soon scans most of Su Lien's chi which the Shadow Master discovers the center of her chi and decides to find out within her consciousness.

At the Dragon Dojo, Tsunami finally informs the Lee brothers that he couldn't save his mentor from their machine because they were too many of them to beat. Billy informs him that he had fought well but cannot overcome evil alone and it is right to come to them. Tsunami also tells him that he knows chi because he is Su Lien's student and decides to go with them and making him a Dragon Warrior to uphold the code of the dragon. With that decision and Billy decides to infiltrate at the catacombs, both brothers cross swords to their transformed state and they put their Dragon Swords into Tsunami who kneels to them and transforming Tsunami into a Dragon Warrior by the name Kona. They finally infiltrated their base as Kona battles Sickle and he demonstrates his power as a Dragon Warrior by wielding blasters on his fists to utilize chi to grapple Sickle down.
