In this clip, Japan-based YouTube user dabu0205 is in some arcade, where his opponent is none other than Daigo Umehara (note the back of his head), perhaps best known for this. He's a fighting game superstar.
Umehara is Street Fighter character Yun, a character he somewhat recently started using. And dabu0205 is the dude getting his ass kicked. Valiant effort, dabu!
