But unfortunately for him, she understood the way he hypnotise them and when he hit her with his staff, she was able to get his bell, and broke the hypnosis.

Battle
Ruin got angry and wanted to kill Elizabeth, but Meliodas stepped in and grabbed his hand. While Meliodas went to see how's Elizabeth, Ruin said that who strikes first, wins, went and hit Meliodas with his staff. While Meliodas was still flying from the hit, Ruin hit him again with his staff pinning him to the ground. Ruin then grabbed Meliodas for the head and lifted him, stating he finds it ridiculous that the kingdom is afraid of such small child. But then Meliodas punched him, and send him several meters away. After stopping Ruin immediately looked up and Meliodas was next to him and punched him again sending him crashing into the Baste Dungeon walls. Ruin seemed uninjured and went out of the rubbish, commenting it would have been boring if it weren't like this. He then explains why were they called Holy Knights, since they had magic imbued into their bodies that transcends man's knowledge. He recommended that Meliodas should draw his sword, since his child fist is soft. Then Ruin with tremendous power started punching Meliodas, hit after a hit, and even Baste Dungeon started to shake. Ruin though that he crushed Meliodas beyond recognition, but then Meliodas went and punched Ruin in the chest and broke his armor. Ruin then said that his body is his true armor, which is stronger that steel, but Meliodas punched him again so hard and defeating Ruin, that almost all of his hand went inside Ruin's body, so started spitting blood. Meliodas mentioned that he couldn't avoid this, since he hurt Elizabeth, someone close to him, and that was his sin.
