Straizo vs. Joseph, Part 2 (ストレイツォＶＳジョセフ その② Sutoreitso Bāsasu Josefu Sono 2), originally The Game Master (ゲームの達人 Gēmu no Tatsujin) in the WSJ release, is the fifth chapter of Battle Tendency and the forty-ninth chapter of the JoJo's Bizarre Adventure manga.
Joseph is resolute to risk his life as he opens fire on Straizo with a Thompson submachine gun, blasting him through the window. He steps inside, and the inhabitants (including Smokey) are either in shock or fearful of him, believing he has killed a man. To Joseph's astonishment, Straizo gets up unscathed. Gloating about the power of the vampires, Straizo attacks him with a ray of vitreous humor, a technique dubbed Space Ripper Stingy Eyes, seemingly piercing Joseph's forehead and throat. However, the Joseph that Straizo damaged turns out to be a reflection in a mirror, and Joseph, abusing the fact that Straizo no longer has a reflection, comes up from behind him and bashes him in the face with the butt of his gun. He immediately charges the gun with the Ripple to attack him.
