Editor's Note

💡 The Comparison. Nearly every reviewer notes the heavy influence of The Novel's Extra. While the setup is almost identical, this story leans more into the Mystery and Demon Hunter aspects rather than just academy life.

The "Oblivious" MC. Fans of the "Misunderstanding" trope will love how side characters over-analyze Seon-woo's every move. However, critics point out that the MC often refuses to clear simple misunderstandings, leading to "forced" drama.

Pacing Warning. Some readers find the first 20 chapters a "slog" due to lackluster world-building, but the quality is said to "go up and up" once the Hunter identity is established.

Experience Curve

Ch. 1–20 (The Slog): ⭐⭐ – The Setup. A standard, somewhat slow introduction to the academy and the "Extra" trope.

Ch. 21–150 (The Hunter Identity): ⭐⭐⭐⭐ – The Hook. Seon-woo establishes his dual life, using the Trait Shop to fix early plot holes and gaining "Causality" points.

Ch. 151–350 (The Butterfly Effect): ⭐⭐⭐⭐⭐ – The Peak. Major deviations from the original story. The "Misunderstanding" trope hits its stride as world-class organizations begin to fear/respect the MC’s hidden power.

Ch. 351–500 (The Forced Mystery): ⭐⭐⭐ – The Plateau. Some frustration arises here as the author withholds key information to maintain suspense, leading to a "slow" feel despite high stakes.

Ch. 501–536 (The Final Resolution): ⭐⭐⭐⭐ – The Finale. All "nets" are pulled in. The truth of the regression and the "Predetermined Future" is revealed, providing a solid, if somewhat safe, conclusion.

WebNovelDB Review

7 /10

A solid "Comfort Read" for fans of the Academy/Extra genre, though it lacks the emotional peaks of its predecessors.

Writing Quality: 7/10. Clear and well-translated (Primordial), though it suffers from "extraneous details" (e.g., long descriptions of walking to lunch).

Character Design: 6.5/10. The MC is likable, but side characters can feel 1-dimensional (the "Interesting..." reaction trope is common).

System Logic: 6/10. Power scaling is a bit vague. Stats often matter less than the "Causality" skills bought from the shop.

Romance/Harem: Subtle. While tagged as harem, it focuses almost entirely on action. The female characters are "useful" allies rather than just trophies.

The Good: The double-identity trope is handled well, providing a nice balance between school life and high-stakes hunting. The misunderstanding humor is top-tier.

The Bad: It feels very "safe." It follows the Novel's Extra blueprint so closely that it rarely surprises experienced readers. The "Mysterious" vibe can feel forced by the author.

For Fans Of: The Novel's Extra, The Author's POV, Academy's Undercover Professor.

Not For You If: You hate "Misunderstanding" plots or want a proactive MC who immediately uses authorities to solve problems.

Verdict: Regressed Extras Become Geniuses is "Premium Slop." It’s better than 90% of the generic extra-genre novels, but it hasn't quite reached the "Masterpiece" status of the books it imitates.
