Manga volumes take 16 of the 20 slots on the list of the top adult graphic novels in the book channel, based on NPD BookScan data for May (5/3/20-5/30/20) provided to ICv2.  But there’s an interesting newcomer… from Korea.

Bong-Joon Ho’s Academy Award-winning movie Parasite gets the graphic novel treatment in Parasite: A Graphic Novel in Storyboards (see "Hachette to Publish Parasite Graphic Novel").  The book was released in mid-May.

The other three non-Japanese titles are hardy perennials: Strange Planet, Watchmen, and They Called Us Enemy.

Turning to manga, as usual, My Hero Academia dominates the list, but the top-selling manga volume in May 2020 was the newest volume of Demon Slayer: Kimetsu no Yaiba.  That’s because there was no new volume of My Hero Academia; VIZ Media has slowed down releases to one every four months, with the next one due out in June.  Kohei Horikoshi’s superhero ensemble action/comedy still has plenty of readers, though; the first volume was the number three seller in May, with volume 2 right behind it, and altogether eight volumes made the list.

Demon Slayer is a rising star that is gaining more readers; the first volume was the number 5 seller, and volume 2 made the list as well.  And keep your eye on Beastars, a shonen story set in a high school where all the students are anthropomorphized animals, some of whom are natural predators of others.  The first volume and the latest volume make the top 20, and the first volume was just nominated for an Eisner Award.
