Return of the Demonic Instructor is a murim time-loop manhwa currently 42 episodes into its official WEBTOON run, with no ending in sight and a reader reception that splits sharply between "ruthless MC done right" and "too much flashback, not enough forward motion."
Reviewing
Return of the Demonic Instructor
TL;DR: Return of the Demonic Instructor updates every Wednesday on WEBTOON, currently at Episode 42 (September 23, 2026) with 10 more episodes app-only. AniList marks it ongoing. Reader reception is mixed: praised for its tone, criticized for pacing.
Key Takeaways
Return of the Demonic Instructor follows Bigang Sa, a human forced into centuries of service in a demon army after humanity loses a war he watched happen once already. A failed uprising sends him back ten years before the invasion, training a new generation of murim fighters with knowledge no one else in this timeline has.
The series is ongoing with a stable weekly schedule and a real, if divided, reader base. It isn't a hidden gem with unanimous praise, the same threads that call the tone and art strong also flag pacing problems in the early chapters. This guide covers where the series stands right now, how to read it, and what to expect from the reception before committing.

Return of the Demonic Instructor: current status and episode count
Return of the Demonic Instructor is ongoing. AniList lists it as releasing, and the official WEBTOON page shows Episode 42 dated September 23, 2026, with the label "UP EVERY WEDNESDAY." WEBTOON's public list is not the complete picture, the page also states that 10 newer episodes are available only through the WEBTOON app, so the browser-visible archive runs behind what app readers already have access to.
The series carries 1 million total views and 41,751 subscribers on its official WEBTOON page as of this check. AniList has no chapter total for the series, so the WEBTOON episode number is the most reliable public checkpoint for how far the English release has gone.
What the credits say
WEBTOON credits MIDNIGHT STUDIO, FISH, and nunmae on the series. AniList records the Korean title as Gwihwanmagyogwan, country of origin South Korea, genres Action and Fantasy.
How it compares to other regression-instructor manhwa
The "protagonist gains future knowledge and starts training a new generation" structure isn't unique to this series. Archmage Curriculum uses the same regression-into-instructor premise in a magic-academy setting instead of a murim one, and carries its own documented slow-pacing complaints about the opening episodes, worth comparing if the flashback criticism here is a dealbreaker. For readers who want the murim training angle without the demon-invasion backstory, Nano Machine is the genre's more established pick, with a longer track record.
Step-by-Step
The safest way to start Return of the Demonic Instructor is the official WEBTOON episode list from Episode 1 forward, tracking the date beside each entry rather than assuming a chapter number from a third-party source.
1. Open the official WEBTOON series page: Use the Return of the Demonic Instructor listing on WEBTOON, not a scanlation mirror. The official page has the current episode count, schedule, and credits in one place.
2. Start with Episode 1: The opening episodes establish the demon invasion Bigang Sa already lived through once, plus the moment he wakes up ten years earlier. Reading from the start makes the time-loop stakes clear before the training-arc chapters begin.
3. Expect a training-heavy middle stretch: Multiple reader threads flag the early-to-mid chapters as flashback-dependent and slower than the premise suggests. Knowing this ahead of time changes the read from "why is this dragging" to "this is a known pacing pattern in this series."
4. Track the episode date, not just the number: Use notes like "Episode 42, September 23, 2026, WEBTOON" instead of a bare number. AniList's blank chapter field means the WEBTOON episode number and date are the only stable public reference point.
5. Use the app if you want to read ahead: WEBTOON's own page states 10 further episodes exist app-only. The browser archive is current but not complete; the app is the only official way to close that gap.
Return of the Demonic Instructor reading order
There is no alternate reading order to navigate here, the series is a single continuous WEBTOON run with no spinoffs, side stories, or separate print/digital splits publicly documented. Read the numbered episodes in order starting from Episode 1. If a future arc introduces flashback chapters or specials placed out of numeric sequence, follow the position WEBTOON's own page gives them rather than reordering by guess.
What readers are saying
Return of the Demonic Instructor's reception on Reddit and WEBTOON's own comment sections is genuinely split, not uniformly positive. A thread titled "[Return of the Demonic Instructor] Is back with two chapters" on r/manhwa shows readers actively tracking new releases, which points to a real, engaged following rather than a series nobody is talking about.
The praise centers on tone: readers who like the series call out how ruthless the lead is willing to be, and generally rate the art as solid. The criticism is consistent across multiple independent reviews: the pacing is slow, and a notable share of the early run leans on flashback sequences rather than forward plot movement. One recurring reader complaint puts the flashback share at roughly 80% of a stretch of chapters, which is worth knowing before starting if flashback-heavy pacing is a dealbreaker.

Tips
Read past the setup before judging the pacing
Because the flashback criticism specifically targets the early-to-mid chapters, readers who bail in the first dozen episodes may be judging the series at its weakest structural point. That isn't a guarantee the back half improves, but it does mean the common complaint is about a specific stretch, not the whole run.
Don't confuse this with other "demonic" or "instructor" titles
Murim and cultivation manhwa both lean heavily on "return," "demonic," and "instructor"-style titles. Double-check the WEBTOON title_no (9262) or the AniList entry (Korean title Gwihwanmagyogwan) if a search result looks close but not exact, several similarly-named series exist across scanlation aggregators with different plots entirely.
Treat scanlation-site chapter counts as unverified
Several non-official aggregators list this series with their own chapter numbering. AniList's own chapter field is blank, and WEBTOON's episode count is the only number this guide verified directly, a different count from an unofficial source isn't automatically wrong, but it isn't confirmed either.

Common Mistakes

Assuming the browser list shows everything
WEBTOON's own notice says 10 newer episodes are app-only. Reading only the browser-visible list and concluding the series updates less often than it does is a real, easy mistake given that gap.
Treating a blank AniList chapter count as zero chapters
A missing chapter total on AniList means the field is empty, not that the series has no chapters. Use the WEBTOON episode number for a real total instead.
