The Twilight Princess manga offers a more mature storyline than the original Zelda manga. The original series, which you can read about below, is geared more toward middle grade readers, while Twilight Princess is more comparable to YA fiction. As such, Twilight Princess is generally a better pick for adult Zelda fans who are interested in reading the manga adaptations.
The 11-volume Twilight Princess Complete Box Set clocks in at 2,040 pages. The manga’s foundation is based on the Twilight Princess video game, but as the longest manga adaptation of a Zelda game, it expands and alters the story of Link and Midna joining forces to keep the Twilight Realm and World of Light safe from evil forces.
If you don’t want to commit to the whole set, you could always check out a couple of the individual volumes first. List prices are $10-$12, though you can get some of them for a few bucks less. Keep in mind that the double-sided Twilight Princess poster is exclusive to the box set.
