I'd suggest beginning with the first chapter. That's where the Tokyo Ghoul world unfolds and you'll get a clear understanding of the setting and characters. It's a great starting point to immerse yourself in the series.
It depends on personal preferences. Some people might think Tokyo Ghoul is better for its original story and character development. Others might prefer Tokyo Ghoul:Re for its continuation and new plot twists.
The Tokyo Ghoul manga is definitely worth reading. The action scenes are exciting, and the character development is compelling. It keeps you hooked from start to finish.
Sure, it's a great manga. It offers a mix of horror, action, and drama. The themes explored are deep and thought-provoking. However, some might find it a bit too dark or violent for their taste.
