Synopsis

Vahn was an atypical youth. Due to a rare mutation, his blood had the potential to target and attack ailments within the human body. Touted as a universal cure, people had elevated his status above the norm and given him the classification “Panacea”. In the media, he was hailed as a great hero who would usher in a new era or human wellness. However, behind the scenes things weren’t so bright. Being a unique individual, Vahn spent his entire youth locked up in a lab with various scientists and research teams using his body and blood to perform endless amounts of experiments. The only solace in his suffering was the various anime and manga made available to him between experiments. He often imagined himself as the protagonist in a world of his own, finally in control of his own destiny. For years he nurtured this desire, until at the age of 14 he died when an organization had tried to kidnap him from the lab…

“Finally, I don’t have to suffer anymore…”

This was Vahn’s last thought as he faded into the endless black abyss…

“You poor soul.”

Editor's Note

💡 This novel is the "Titan of Fanfiction"—a massive, 2,300+ chapter odyssey that dominates the Danmachi (Is It Wrong to Try to Pick Up Girls in a Dungeon?) fan-fiction space. It is a story of extreme contrasts: it begins as a poignant, psychological study of a "broken child" and evolves into an expansive, smut-heavy harem empire. It is widely considered the "gold standard" for technical writing quality and update stability, while simultaneously being a lightning rod for criticism regarding its "infinite" romance subplots.

The Harem Behemoth. This isn't just a story; it's a commitment. Vahn Mason is a protagonist built on the concept of "The Panacea"—a boy whose blood heals but whose spirit was shattered by a life of laboratory torture. The early chapters are incredibly high-quality, exploring his "zero-common-sense" approach to freedom. However, be warned: the story shifts heavily into a "Slice of Life/Smut" loop where the MC collects almost every female character in the source material. It is the literary equivalent of a "100% Completionist" run of a dating sim.

"He wanted to heal the world with his blood, but he ended up conquering it with his heart (and his bed)."

*2365 chapters of trauma, smut, and cosmic polyamory. Complete — if you survive the sugar rush.*

Experience Curve

Ch. 1–140 (The Golden Age): ⭐⭐⭐⭐⭐ – Excellent pacing. The struggle for survival in Orario, the forge mechanics, and Vahn’s genuine trauma make for a top-tier read.

Ch. 141–600 (The Harem Explosion): ⭐⭐ – The "Diabetic Coma." This is where most readers drop the novel. The story veers into non-stop romance drama and smut. Action becomes secondary to "harem management."

Ch. 600–2,300+ (The Multiverse Expansion): ⭐⭐⭐ – If you survive the harem bloat, the scale becomes massive. The world-building expands into other universes, and the stakes shift from "survival" to "godhood."

WebNovelDB Review

8 /10

A technical masterpiece of writing and dedication, though its "Infinite Harem" may prove too sugary for fans of pure action.

Writing Quality: 10/10. For a Webnovel, the grammar and prose are impeccable. The author is a professional in terms of update consistency and descriptive detail.

Character Design (Vahn): 6/10. While his backstory is tragic and compelling, his later development into a "socialite God" who can't say no to any woman makes him feel like a generic wish-fulfillment vessel for some.

Romance/Smut: 10/10 (Quantity) / 4/10 (Realism). If you want an endless parade of beautiful girls and detailed encounters, this is your holy grail. If you want a focused, realistic romance, look elsewhere.

World Building: 9/10. The author takes the Danmachi lore and pushes it to its absolute limits, adding tiers, systems, and logic that surpass the original light novels.

The Archetype: The "Harem King" Completist. You enjoy long-form stories where the MC fixes every tragedy, saves every girl, and builds a massive family. You don't mind a "Slice of Life" pace where combat is sometimes a side dish to relationship drama.

Not For You If: You hate "Slutty" character shifts (where strong female characters fall in love instantly). If you want a "Lone Wolf" or "Action-Only" protagonist, Vahn Mason will frustrate you within 100 chapters.

Core Worlds: Starts in Danmachi (Orario), but expands into Fate/stay night, Type-Moon lore, and beyond.

Harem Note: This is not a 'harem' in the traditional sense. It is a 'polyamorous empire.' Vahn ends up with dozens of partners. If that number makes you uncomfortable, stop at chapter 140 and pretend the novel ended there.
