In a simplistic small room with figurines and posters, a young man was on a computer trying to get through his day.
"Hahaha! I love these novels, if only I could be the op protagonist instead…" He sighed as he lay back on his sliding chair.
Right then, reality heard his wish.
In an instant, he fell to the ground a white space surrounded him.
And following this sudden change, a floating screen appeared.
[You have been selected for Project Fiction, would you like to participate? It will allow your wishes to come true.]
"What?! The hell?!… No way… I was just in my room… How?… It can't be real, right?" He backed away from the screen and looked around in confusion.
The screen popped up in front of him again.
[Respond. Will you take part in Project Fiction? Yes or No?]
Too stunned to speak, he fell on his bottom again and sat down to take in the situation.
(Man! This is it! It's happening!… Wait, it could be dangerous… But I don't care! I would not miss this chance if it damned me!) He nodded to himself.
No words came out of his mouth, as he could not believe this was real, it had to be a dream or a hallucination of some kind, he didn't even die like the typical protagonist would have to, for this.
"I… Yes?" Unsure of what to even make of the situation he just went with his gut feeling.
[Perfect. You have been studied extensively and a system denominated: 'Fiction Harem Sovereign System' has been assigned to you. You will be sent to various fictional worlds and have to experience their story from beginning to end. Change it as much as you wish, but you must survive until the end, failure to do so will result in severe punishment. Due to your perverse personality, as plot-mandated restrictions to content or tone have been removed.]
"Huh… So, even in a world that's not dangerous, I could still die? Is that it?" He asked still breathing fast from everything going on.
[Correct. In every world you visit, you will be reborn with three goals, get the fictional core of that world, become the most powerful, and have at least all the named female characters in your harem.]
"Heh?! Really?! I can just do that. This is really too good to be real… Why?" Even in his excitement, something in him pushed him to question it.
[Response. To create an Heir. This is a trial, and if you fail to complete the requirements in any one world, you are disqualified and will face severe punishment.]
"… That sounds amazing… Just who is giving me such a great chance?" Now curious he asked.
[Inapplicable. You don't have clearance to receive such information. Become powerful enough, and use your system to request an audience, and then I will answer that question.]
"Of course… regardless… I'll get to live in those worlds!… Actually, how many worlds?" He turned to the floating screen again.
[Response. All the fiction worlds you fully experienced or loved. Every single one.]
"What?! That's way too many! I'll die of… Oh yeah, I'll reincarnate, so that's not a problem. Still! Some of those worlds are way too dangerous! I have no powers!" He yelled.
[Affirmative. At first you will be restricted to tier 1 worlds. Meaning worlds that are mostly not that powerful with a few exceptions. Nothing too extreme.]
"… Ok, that's good… So, do I just go now?" He sighed in relief.
[Create your character. Whatever core features you select will stick through every world, so be wise. You will make all his look, and choose 3 abilities from a list.]
"Ok… I can do this…" He nodded his head.
In terms of looks, he ended up doing whatever he wanted.
He possessed a striking appearance, with dark brown skin that glowed under subtle lighting and sharp, angular features that conveyed a sense of quiet confidence.
His hair was a vibrant shade of purple, tousled and spiky in a messy yet deliberate style that framed his face, falling just above his shoulders in uneven strands.
His eyes were an intense pink, almond-shaped with a piercing gaze that held a hint of mischief, complemented by thick lashes and slightly arched brows.
A subtle smirk played on his full lips, revealing straight white teeth, while his jawline was defined and chiseled without being overly pronounced.
He wore a black hoodie pulled up slightly at the collar, revealing a glimpse of a white shirt underneath, and his neck transitioned smoothly into broad yet proportionate shoulders.
His body was perfectly toned, featuring compact muscles that suggested agility and strength without bulkiness—lean and defined, like that of a disciplined athlete who favored precision over sheer size.
Then the time to choose 3 powers came, and he chose unusual abilities, which didn't really guarantee success.
Magical Cock
Also Called
Enchanted Phallus
Sorcerous Member
Mystic Manhood
Capabilities
The user possesses a penis (or equivalent organ) that is imbued with magical properties, granting it supernatural abilities beyond mere biological function. This appendage can channel arcane energies, cast spells, or alter reality in ways tied to its form and use, often blending sexual acts with mystical effects. The magic may stem from innate power, a curse, artifact enhancement, or divine blessing, allowing the user to wield it as a wand-like focus or autonomous entity.
Applications
Spellcasting via Intercourse: Perform rituals or incantations through sexual activity, such as healing, summoning, or transmutation during climax.
Energy Projection: Emit blasts of magical force, illusions, or elemental attacks from the tip.
Enchantment Infusion: Imbue objects or beings touched by the organ with temporary magical effects, like enhanced strength or invisibility.
Shape-Shifting Organ: Alter the size, shape, or properties of the penis to adapt to situations, such as extending for reach or hardening to diamond-like durability.

Hentai Protagonist Archetype
Also Called
Anime Erotica Hero
Lewd Plot Armor
Ecchi Lead Physiology
Capabilities
The user embodies the archetype of a protagonist from hentai (Japanese erotic anime/manga), granting them extraordinary luck, resilience, and narrative convenience in sexual or romantic scenarios. This power warps probability and social dynamics to favor the user, turning everyday situations into opportunities for explicit encounters, while providing immunity to typical consequences like rejection, injury, or social fallout. It functions as a meta-ability, treating the user's life as a scripted story where they are the unbeatable lead.
Applications

Convenient Coincidences: Events align to create erotic setups, such as accidental undressings or isolated encounters.

Ineffective against individuals with strong wills or anti-trope powers.
Narrative "endings" might force resolution, such as commitment or loss.

Betrayal Inducement Anatomy
Capabilities
The user possesses a body that inherently provokes or facilitates netorare (NTR) scenarios, a genre trope where romantic partners are "stolen" through seduction, coercion, or superiority. This physiology enhances physical allure, pheromones, or subtle manipulations to erode relationships, making the user an irresistible interloper or victim. It can be offensive (as the "stealer") or defensive (as the one being stolen), altering emotions, loyalties, and desires in targeted couplings.
Applications
Seduction Amplification: Heighten attractiveness to break bonds, causing infidelity or switches in affection.
Emotional Erosion: Induce doubt, jealousy, or dissatisfaction in relationships via aura or touch.
