For all who have Problems with Genu: just don't give up. I had 8-9 tries until i know his tactic and defeated him. Don't release the spacebar, to be sure every space between his shield will be a hit on him. Buy much Boss Killers, you need them to Max your damage. Use Healing technique and stealth to survive. Good Luck!
