Street Fighter II: V - 1x06 - Season 1, Episode 6- Followmy.tv

In this episode, Ryu, Ken, and Chun Li go shopping at a shopping mall. Once there, Ryu meets a strange old man who it seems is about to die, as he is sweating, and looks to be in bad condition. Ryu says he will call an ambulance for him, but the old man insists on Ryu taking him to a place of privacy. There, the old man practices a martial arts technique in front of Ryu, where he uses his ki to create a blue fireball from his hands. He swallows this fireball, and, after it explodes in his stomach, he's fine and back in good health. Ryu wants to learn how to do the technique the old man just did, and so he takes him to his shop where they can have privacy and practice the technique. Ryu doesn't master it, although he gains a little more knowledge about his spiritual self after this encounter.
