Hamon Teacher Lisa Lisa, Part 1 (波紋教師 リサリサ その① Hamon Kyōshi Risa Risa Sono 1), originally The Master of Venice (ヴェネチアの達人 Venechia no Tatsujin) in the WSJ release, is the twenty-seventh chapter of Battle Tendency and the seventy-first chapter of the JoJo's Bizarre Adventure manga.
A doctor examines Joseph and is astonished at the sight of two rings perfectly fused to his organs. Since current surgical techniques do not allow Joseph to have them extracted, Caesar proposes to simply defeat the Pillar Men within 33 days. He demonstrates how untrained Joseph in the art of the Ripple by making him hold a cup of water upside down. Joseph's lack of concentration, a skill essential in producing a powerful Ripple, works against him, causing the water to spill out. Thus, Caesar brings him to Venice to have his master teach him.
In Venice, Joseph doesn't understand how he can learn of the Ripple here. At this moment, a gondolier Caesar called confronts Joseph and masterfully uses the Ripple to beat Joseph. Joseph is sent into the water but manages to stay over the water, impressing the gondolier.
