We recently launched the high-resolution version of my webcomic Toggle. It's 40+ pages of the first volume of the comic.
SYNOPSIS:
Ray joins a mathematics club at her new school. However, things are not as they look. The club proves to be more than just research when Ray realizes SHE IS THE RESEARCH SUBJECT!
If you are on the fence about it, you can watch the anime version for a quick summary.
OR search for it on your webcomic app of choice.
