Yeah, I know a lot of people weren't really fond of the protagonist, but in my opinion, he was probably one of the best protagonist I have ever come across, lmao. He didn't stray from his goal despite uncovering his past and going through all that drama, he still remained free. I was actually pretty surprise when Hakka turned out to be the mastermind behind everything and Colonel Gia was actually playing the good guy; I didn't see it coming, lol.
For once, the female lead(?) wasn't typically annoying or shoved all the way in the background (not that I mind?), in fact, she played a pretty powerful role, and I overall liked her character a lot despite her ending. In my opinion, I think she fell in love with Zen, maybe, perhaps? Or at least, something akin to it, because Zen was the first person who didn't treat her like she was something fragile, and was the first person to tell her to control her own life. With what Zen "taught" her, she grew stronger into what she believed in.
Everyone in this manga had their own sense of "justice" --- ah, well, besides Zen? Which was a nice read, no one was annoying either, lmao, also, if everyone's wondering why they're all so young looking, ... LOL ;; Zen's a human experiment, so he probably stopped aging and adapted to his "supposedly" forever age, and well, there's a mystery behind Hakka, orz ;; But he is the doctor who once controlled Zen, 😛
But yeah, reading this manga was very beautiful, I want to buy the books, orz;; If there was one thing to criticize, it would probably be the length? But I was satisfied with the ending, too. Though, I want to see more of Zen's adventures D: Uwah ;; The art is ridiculously pretty, and Zen wasn't too feminine, he was in fact, perfect, imo.
