Seems tasty, I especially like the "romantic" background in the first panels, title?
It's Gosu (The Master). It's the most complete and whole shonen to date in my opinion, since:
- it's filled with simple but impactful characters, Red Herrings, reveal, and the storytelling is so beautiful, especially in the earlier and middle part.
- The protagonist is a solid protagonist, he has awesome story, complexity, and reasonable motivation, solid pro and con.
- The battle was so explosive and creatively depicted. In the last arc though, the author get lymphoma so i can see the decline in both storytelling and fight explosiveness and creativity. It does drag quite a bit in the last 2-3 major fights, but that's the most complaint i can think about Gosu.
- it doesn't overstay its welcome. The author had clear plot roadmap in mind. The manhwa is completed and it's satisfying.
