Anime's increasing popularity is undeniable, but many people who aren't too familiar with the animation style don't realize that it can cover a lot more adventure than stories like One Piece and Dragon Ball Z. A less common theme tackled in anime is historical fiction, but one good representative of the subgenre is coming to Netflix this summer. This week, the streamer confirmed that Leviathan is debuting on the platform and announced a release date: the new anime premieres on July 10.
