Review Detail of Kaliedo in Once Human, Now a Parasite

This had some potential but it feels like you wrote yourself into a corner at the very beginning with the MC being given an incredibly powerful ability. Which leads to you having the MC overlook obvious ways of getting stronger simply so something in the immediate future remains a threat. It also doesn't help that you make the MC incredibly inconsistent in terms of goals and personality. For example, in the beginning the MC is new to the world, possesses a skeleton and enters the nearest town with the goal of remaining low profile and learning about this new world and its dangers, as in who and what to be wary of. He finds a book store, buys all the relevant literature and decides its no long an immediate concern to read them and goes for a stroll... in a body, he already noted attracted attention due to the chilling feel it gave to those nearby. He happens upon an auction, the items of which are mostly sold to a man who is clearly rich and powerful in status as he not only bids high but no one dares bid higher and chance offending him. That is until the last 'item' a slave. Now, it should be mentioned that before the MC even entered this town he came across a bandit camp with slaves, as can be imagined horrible things were done to the slaves and he killed all the bandits as well as mercy killed one of the slaves who endured too much. As for rest despite his anger (which he shouldn't be feeling as X sealed it) he doesn't help them, he just leaves. Back to the auction, the 'item' is revealed as a beautiful demon-girl slave, he doesn't know her story, he has no reason to care for her in any way but for reasons, she gains his attention and he decides to buy her... to gather information... he then keeps doubling the bid of the rich and powerful royal until he wins for a total of 2 million gold. I feel like I should repeat that his goal before all this was to lay low and learn about the world and he keeps flip-flopping like this throughout the novel. In the end he feels less like a character and more like a plot device, he's whatever you want him to be at any given moment so you can drive the story in your desired direction, regardless of his personal history or personality. I can also get into story pacing but I think I'll stop here or this is going to get ridiculously long.
