Manga continues to be a popular and growing genre in the United States, as seen in the NPD BookScan's Top 20 adult graphic novels list for February. This month's list features 19 manga volumes, with Kōhei Horikoshi's My Hero Academia taking the top spot with volume 33.

My Hero Academia is a superhero manga that follows the story of a boy named Izuku Midoriya who dreams of becoming a hero despite being born without powers in a world where having superpowers is the norm. The series has gained a huge following since its debut in 2014 and has been adapted into an anime series and multiple films. Its continued popularity is reflected in the sales of the manga, with both volume 33 and volume 1 appearing on the February bestsellers list.

Another manga that stood out on the list is Tatsuki Fujimoto's Chainsaw Man, with multiple volumes appearing in the top 20. The series follows the story of a young man named Denji who becomes a devil hunter after merging with his pet devil Pochita, who transforms into a chainsaw. The manga has gained a lot of attention for its unique premise and has been praised for its storytelling and art style.

The presence of manga on this list shows that the genre continues to have a strong following and market in the United States. Manga has become more accessible in recent years, with many titles available in local bookstores and online retailers. The popularity of anime adaptations has also helped to introduce manga to a wider audience.

It's worth noting that manga isn't just for young readers - the term "adult" in NPD BookScan's Top 20 adult graphic novels list refers to the target demographic rather than the content of the books. Manga covers a wide range of genres and themes, from action-packed shonen titles to romantic shojo stories and everything in between.

Overall, the NPD BookScan's Top 20 adult graphic novels list for February shows the continued popularity and growth of manga in the United States. Whether you're a longtime manga fan or a newcomer looking to explore the genre, there's no shortage of titles to choose from.
