Uesaka Sumire *(Narration PV)*

A 17-year-old high school girl in Tokyo, she is transported to another world after being hit by a truck while shopping for a school festival. At her school, she had a boyfriend who was a member of the soccer club, and she was in the so-called upper caste. When she was transferred to another world, she met God, but she did not receive any skills at that time, and Chiba, who was transferred together with her, thought that she did not have any skills.

A non-virgin because she was deceived in junior high school and used to have a compensated relationship. Since she cannot return to her original world, she works at the bar and brothel "Blue Cat Nocturne" to make a living. She has a bright and positive personality by nature, and since she works, she aims to be higher, actively interacting with other prostitutes, doing chores from the role of livening up the shop (otagei), and dealing with unpleasant customers and rough people. Deal with customers, etc.

Originally, he had long brown hair with pink ash, but he didn't like customers pulling his hair like a reins, so he had a medium bob hairstyle, but he tied his left sideburn long. He wears a flared dress that reveals his chest. Although he has slender limbs, customers sometimes point out his underdeveloped buttocks and refuse to be nominated, and he burns with rivalry against plump women like senior prostitutes Shikraso and Kiyori. Although he is favored by Chiba, he hates Chiba from the bottom of his heart, who was a shy otaku in his original world, and in fact, by feeling with his skin that Chiba reveals his true nature, hopefully in the future. Although I personally hope that we will no longer be involved, it is also a presence that I feel familiar with as people who came from the same world. On the other hand, although he does not have romantic feelings for Smove, who is also favored, he treats him as a younger brother with a promising future, and has no ill feelings.

She visits "Blue Cat Nocturne" only on rainy days, and is attracted to the "Silver-Haired Uncle" who only drinks sake and comes home. After she was bought once, she became obsessed and longed for the reunion. In fact, soon after I started working at "Blue Cat Nocturne", God came as a guest, and at that time, I was given the skill 「*Creative Pregnancy*」, and I completely copied the skill and level of the man who held me. This is the reason why Haru was particular about ejaculating in his womb when he was held by a customer in the work. Furthermore, by being embraced by Smove, he acquired his skill "Infinite Level", so the level cap has disappeared. However, in this world where women cannot become adventurers, it doesn't make much sense. Skills and levels have not been copied from "Silver-Haired Uncle".

Using the skills she has acquired, she sexually hurts Cyclaso, slaughters and annihilates the soldiers who drove her to death, and at the end of the story, thanks to the benefits and efforts of the skills copied from the guests she has taken so far. she has been promoted to No. 3 sales of the store. From Chiba's information, he learns that the way to return to the original world is to "defeat the demon king", but Chiba has no motivation, so he wants to defeat the demon king himself and return to the original world and the slaughter that deviated from the daily life of the original world, he eventually stopped returning to the original world.

After being scouted by WidgeCraft as a party member in the sequel to summer, he began to go on adventures in the forest to subjugate monsters. However, as a result of confronting her and confronting her with her true feelings, she became pregnant with a "silver-haired uncle".

### Abilities

Haru started working at "*Blue Cat Nocturne*", God came as a guest, and at that time, I was given the skill 「*Creative Pregnancy*」, and she completely copied the skill and level of the man who held me. This is the reason why Haru was particular about ejaculating in his womb when he was held by a customer in the work.

* ***Creation Pregnancy*:** The cheat skill granted to Haru by God. When a man ejaculates in Haru she will receive a copy of his experience points and skills. Using this Haru has reached level 387 and gained the following skills:
	+ *16x Experience Points*: Gains 16x more experience points than others for the same actions.
	+ *Immunity to Status Effects*: This skill makes the user immune to any kind of Status Effect.
	+ *Immunity to Attack Magic*: This skill makes the user immune to any offensive magic directed at her. In effect, it manifests as a kind of invisible barrier, but even effects produced right at the body can be negated.
	+ *Level Bind*: This skill allows the user to suppress their level and selectively deactivate their skills. Haru usually uses this to appear normal.
	+ *Status List*: This skill allows the user to view all her own skills. In Haru's case it especially also shows from whom she got which skills and exp.
	+ *Skill Killer*: Negates all of the opponents' skills.
	+ *Sage's Wisdom*: This skill turns Haru into a more powerful magic user than even professional mages.
		- *Ice Magic*: Haru can use Ice Magic and use it to freeze water on the ground and by that the feet of opponents unto the ground.
		- *Air Magic*: Haru can use Air Magic to produce a cutting attack.
		- *Lightning Magic*: Haru has demonstrated creating some lightning in her hand.
	+ *Summon Ice Elemental;* *Sivyl Unico*: Creates a blue egg, which continues to expand and in the process of doing so freezes the entire area. Once it hatches the area is destroyed.
	+ *Summon Fire Elemental;* *Ganegudey Drago*: Creates a red egg, which continues to expand and in doing so burns the entire area. Once it hatches the area is destroyed. By combining this and the Ice Elemental Haru can create an explosion of blinding light, that was strong enough to "melt" the trees surrounding her in a forest.
	+ *Dual Spell*: This skill allows Haru to cast two spells at once.
	+ *Sword Fighting +150*: This skill makes Haru an excellent swordswoman. Even the average well-drilled soldier has only +10 in this skill. Using this she can instantly mimic other swordsman's techniques and precisely realize the movements she wishes to accomplish.
	+ *Martial Arts +120*: A cheat skill that vastly increases her prowess in martial arts. Similar to her sword fighting skill, this should allow her to easily mimic any martial arts technique she has once seen. Additionally, Haru has actually done some Judo as a child and is capable of judo throwing a man even without this skill.
	+ *Equestrian Ability +80*: This skill grants the user the ability to expertly ride and handle horses.
	+ *Speed +140*: Greatly increases the user's speed. A soldier that was known to have a "godspeed blade" only has +80 in this skill.
	+ *Emotion Killer*: This skill allows the user to disable their emotions at will. This can also be used to let them endure pain.
	+ *Super Great Singing*: Enables the user to sing very well.
	+ *Bind*: Makes the user skilled in tying others up. This includes putting pressure on joints so that even a superhuman can’t break out of simple ropes.
	+ *Dig*: Allows for the digging of holes. Useful for creating pitfalls.

Haru has many skills mentioned only in name. For the most part what they do is evident from the name: *Accuracy +100, Dynamic Visual Acuity: Divine, Reaction Speed: Light, Beautiful Skin, Gorgeous Ass, Cooking, Carpentry, Survival, Tracking, Double Blade, Peripheral Vision: Cosmic, Instadeath Immunity, Fire Magic, Earth Magic, Summoning Magic, Bastard Sword, Charge Spear, Aegis, Embody Armament Concept, Sermon to Eradicate Dead Souls.*

Furthermore, by being embraced by Smove, he acquired his skill 「Infinite Level」, so the level cap has disappeared.

* *Unlimited Levels*: Usually humans have a level cap, preventing them from growing beyond a certain point. This skill makes it so that the user can infinitely continue growing without restriction.

## Reception

*JK Haru is a Sex Worker in Another World* won an award in the doujinshi, or private publication category at the BookWalker Grand Prix Awards 2019 from digital publisher BookWalker. The work was also BookWalker's sixth best-selling e-book of 2019. In the 2019 edition of the annually published light novel guide *Kono Light Novel ga Sugoi!*, *JK Haru is a Sex Worker in Another World* was listed at number seven in the tankobon category.

Kim Morrissy wrote in her column "The Best (and worst) Isekai Light Novels" on Anime News Network that *JK Haru is a Sex Worker in Another World* is embracing the isekai genre in a much darker and more deranged manner as a commentary on the genre. In it, the female protagonist Haru is thrown into a misogynist fantasy world and has to work as a prostitute to survive, while her classmate, who has also been teleported into this world, is endowed with superhuman powers. Morrissy interprets this as a mirror for how these medieval-looking worlds of this genre are particularly restrictive towards women, while male characters are not confronted with such situations due to their privileges.
