This is a list of the Viz Signature and Shonen Sunday (excluding any Shojo/Josei in the Signature line) imprint manga that have been published physically in English (so it doesn't include any digital-exclusives that would be found on Manga+ or SJ app). This also doesn't include any of Viz's Shonen Jump imprint titles.
I got annoyed that someone said Viz release more Shojo than Shonen, so I made this list to put into perspective total Shonen Jump (and now Shonen Sunday and Viz Signature) releases vs the already existing Shojo Beat release interest stacks
Not dealing with Light Novels here either
I've left off a bunch of Junji Ito's anthologies since they include both shojo and seinen manga in the anthologies
