Later, after training with his new powers, Ryouga, Miruto and Yappy encounter a street performer named Rabine sleeping in the woods. After Rabine runs off, they chase him and end up in a small area with a vending machine in the middle. Yappy manages to figure out how to get it to move, revealing a secret passage underneath it. The group goes down the stairs and ends up in a tournament for Burst Warriors known as Burst Heart Survival.
There, Ryouga meets several other Burst Warriors along with meeting up with Carola and Hariru again. Using his Burst, Ryouga passes the first round, Suddenly Bottomless Survival, and moves onto the second one. Due to Miruto and Yappy not being Burst Warriors, they are kidnapped by the tournaments navigator, Pauline, and are held for ransom. In the second round, Box Escape Survival, Ryouga is paired up against the young ninja Karuta who has entered BHS to heal his disease-plagued village. Figuring out how to escape the box they are trapped in, Ryouga and Karuta manage to pass onto the next round, Add
Up To Ten Survival.
