I love Zeus but I feel bad for him. He has like no social skills and since he never interacted with people much before coming to the Demon King Castle, he has no idea what is considered normal behavior. That's probably why he didn't find what Poseidon was doing weird. Everyone was afraid of him since he was some super strong god and they didn't want to make him angry. Even the demons was scared of pissing him off when he first came. Zeus is the type of guy that would probably get scammed with how clueless he is. It's a good thing that he has two older brothers that really care about him and will probably beat up anyone that tries to do anything to him. I'm glad he has friends now and I hope to see more of him in the future.
