I've heard that guideverse/sentinel-guide AU stems from the show "The Sentinel," so I see how sentinel and guides are a thing, but how did espers come about?
Chinese manhua that features guideverse appear to stick with sentinels, and I've only so far seen espers specifically appear in manhwa, so I was wondering if it was a term coined from Korea? Or perhaps something else?
Loved this manga...but oh my gosh I didn't realize I read them in the wrong order, time to go read the prequel I guess?? lol
Edit: I read the prequel series and now I feel empty. It's such a sweet story.
I hope to get my hands on a physical copy someday!!
