Well, one way is to look for authorized digital stores that offer Baki manga. Sometimes libraries also have digital collections that you can access with a membership. Another option could be to check if there are any official streaming services that carry it.
I think you should start with the earliest published Baki manga. That way, you can follow the evolution of the story and characters in the correct chronological order and fully appreciate the depth and development of the series.
You could look on platforms like Crunchyroll or Funimation. They often have a wide range of anime, including Baki. Another option is to search on YouTube, though the availability might vary and the quality might not always be the best.
Blade Fangs was a Japanese manga created by Itagaki Keisuke. There were four works in total, namely Grappler Blade Fangs, Fanma Blade Fangs, Blade Fangs Path, and Blade Fangs Path 2. The theme of this manga was hand-to-hand combat, and it told the story of the young Blade Fang fighting with strong enemies in various underground arena competitions. The characters in the Blade Fangs series had distinct personalities, compact storylines, and unique styles. This series of comics was well-known in China and was welcomed and loved. The animated version of Blade Fangs also had two seasons and could be watched online. As for the viewing order of Blade Fangs, they could be viewed in the order of Blade Fangs 1, Blade Fangs 2, Fanma Blade Fangs, Blade Fangs Path, and Blade Fangs Path 2.
They might be quite surprised. Some characters could find it interesting to see different interpretations of their own stories. For example, a character might be amused by a fanfiction that gives them a more heroic role than they originally had in the Grappler Baki series.
