Tower of God
The art style kept me off this for a long time, but I finally decided to read the first few chapters. Before I knew it, I was in chapter 30 without realizing. The story is that engaging, and the story is deep and complex, like a huge beautiful flower slowly unfurling its petals as it blooms. This is past 480 chapters, and the character development, the side arcs, all come together seamlessly. The art keeps getting better and better as it goes along. One of the best stories I've read to date.
Noblesse
I had a hard time understanding the MC's character and intentions at the beginning. But as the story developed, things started to make sense. The story starts of like a little slice of life with action in between, but it grew into major plot lines and mysteries that kept me engaged. The artwork got seriously better. Badass characters, comic ones too and even more badass OP MC, this ones gets better the more you get in to it. So much character development, and each character is perfectly highlighted without being overlooked.
Noblesse: Rai's Adventure
A short sidestory of Raizel prior to the events of Noblesse.
Eleceed
Dont judge this one by the cover lol, this is a great story, its got a badass MC and another wholesome MC as well. The art is amazeballs, the dialogue is on point,(seriously) great character development and theirs enough humour to make you cackle, and yes its mostly the cat. This is a weak to strong, mentor mentee journey that continues to impress as more chapters come along.
The God of High School
There is a lot happening in this manga, and some of the parts are a little dragged out. However it does have awesome fight scenes to compensate and a lot of awesome panels. If you can wait out the dragged bits, there are really good moments. However, the MC appears less and less as it goes on, and the story as a whole takes precedence. Good character development as a whole, but for once i'd rather know some purpose to the story by 150+ chapters.
