Hiro still remembered what he had to do to open the gate of sins which was now covered by that disgusting object. He didn't know what Cara had just done until it was considered an act of cheating.
"What have you done, Cara?" Hiro asked without beating around the bush. He couldn't come up with a solution to save the girl without knowing the original cause.
"Well, I saw a closed gate then a bang it using all of my power. That's all, and suddenly this thing came out. Are you going to just sit there and do nothing to this thing, NightFall?" Cara was really already very upset. Her hands and feet were tied up. She could only squirm a little.
The last time Hiro opened the gate, he had to activate the seven deadly sins. That was the condition. However, before he could do that… Hiro had to knock on the gate three times.
