I know that Nakaba decided to make Percival the protagonist because he didn't want to continue with the children of sins, but that's no use when his protagonist is practically a copy of Meliodas, the same look, the same ecchi, the same sword, I mean, what would the problem to continue with the children of sins? I don't see a problem, and besides I found Tristan and Lancelot much more charismatic than percival, I really can't find him charismatic, having stayed with the children of sins was a safer bet, as everyone who likes them would give another chance to your children. Percival however will have to win over his audience with his charisma, something I can't see in him, in 1 chapter only Tristan and Lancelot have proven themselves more charismatic than Percival.
