If you need a comic that won't run out, you can try EGS. A comic about teens running into a wide variety of supernatural stuff. https://www.egscomics.com/
It's been running since 2002 and still going. And while the early arc are pretty rough in both art style and writing quality, it gets progressively better as the author matures.
Another comic I love is Sleepless Domain, a dark magical girl story about a locked down city that comes under monster attack every night. https://www.sleeplessdomain.com/
I found both of these through https://hiveworkscomics.com/ which is another, though smaller comic repository like Webtoons.
