Review Detail of Trident in Dragon Ga Kill [Original]

Sigh....what a blunder....actually this story is pretty good but at the same time pretty ****ed up, why? Because at one chapter the author made the mc lost half of his memory ( it mean he indeed still has his killer skill and still has his akame ga kill knowledge) but after that chapter the author decide to change from half-memory to fragmented memory ( it mean that he has full memory both past life skill and past life knowledge but he has to connect them piece by piece ) why did i say its good but ****ed up at the same time? Because the author was a fucking troll that didnt not explain the change of plan.
