The Player

The player is the unnamed main protagonist of HuniePop. They are lead through the beginning by Kyu, who takes them on one training date. After it, she gives them the Huniebee, which they use to meet more women. Kyu, as a love fairy was tasked to them to alleviate their awkwardness until they had no problem talking to women, and was able to have sex with all of them.

By the end of the game, they've gathered an entire harem, consisting of 12 women whom they take on dates, earning Munie (in-game money) after each date. They can also earn Hunie, another in-game resource, which can be used to upgrade traits.

At the end of the game, they have sex with and effectively conquer Venus, after which Kyu will congratulate them and request panties from all the girls. This will activate "Alpha Mode" where dates become harder and harder, effectively becoming an endless mode seeing how far the player can get.

The player character reprises their role in HuniePop 2. At the beginning of the game, the protagonist is immediately shown to be engaged in a sexual encounter with an as of yet unseen girl who shortly afterwards turns out to be Ashley. Shortly following the conclusion of the coitus, the protagonist bids Ashley farewell for the night, and is promptly greeted by Kyu, who has returned to request their aid in defeating the Nymphojinn. The protagonist makes brief small talk with Kyu upon seeing her for the first time in approximately two years, after which Kyu informs the protagonist of the situation. The pair depart for Inna De Poona the very next day.

Upon the flight, the protagonist receives additional briefing from Kyu (as well as an explanation of double dates), notices Lola on the flight, and begins the tutorial 'double date' inside of the plane bathroom while Kyu watches and advises from inside of the protagonist's mind, informing the player (and subsequently, the protagonist) that they are unable to fail this date. The protagonist also learns that Kyu has been forbidden from having sex with clients, which results in Kyu only being able to watch the encounter.

After catching up with Lola, the protagonist engages in the sex phase of the tutorial. The player is shown a CG of Lola and Kyu in the plane bathroom, and after the flight lands, the protagonist checks in, begins meeting girls, gets to know their baggage, dates them, and has threeways with them.

Appearance
The player's actual appearance is never shown. In terms of height, they are on almost all of the girls' eye levels. This is most likely done for convenience of perspective considering the varied heights of the women. As per in-game dialogue, they seem to be a young adult, about the age of a college student (implied when Tiffany asks them if they are going to enroll this year). If the player is male, their seminal fluid can be seen on the women after sex. This does not apply if the protagonist is a female. As it is implied that the player's only flaw is their lack of social skills, they are likely good-looking as they are able to date anyone they want (In addition - one of their dates, Tiffany, admits she would never date someone unattractive even if she liked their personality) and are only hindered by courage.

Personality
At the start of HuniePop, the player comes off as a loner who finds it difficult to talk to women, being very jittery and nervous around Kyu upon first meeting her. Eventually, the player becomes more adventurous and more confident during the course of the game and will start talking to girls, giving them gifts, and after enough dates, will have sex with them.

As the player progresses through the game meeting more women, they become much less nervous, and escalate their ego to the point where they become a womanizer, increasing their social skills and having sex with every girl.

HuniePot Dev remarked on Twitter how much of a "POS" The Player is because "he banged a girl and her mom".

The player also seems to have a knack for remembering specific details, right down to the girls' birthdays and even weights.

In HuniePop 2, the protagonist is noticeably more confident (as well as vulgar), indicated by the bolder and sassier dialogue options presented to the player in comparison to the first HuniePop. During the timeskip between the two games, the protagonist is mentioned to have been having casual sex with many girls, especially Ashley, on a regular basis since the end of the first game.

The protagonist seems deeply unnerved when Zoey meets them for the first time, as she immediately discusses knowledge with the protagonist that she logically should not be privy to.

Trivia

 * The two protagonists in each game are not the same person, proven through Audrey; her description remarks that she was driven into the camming business due to finding out she was being cheated on with multiple other women, and it would not stand to reason why she would work for the same person that drove her into a deep depression.
 * The term 'player' could serve as a sneaky double entendre, as someone who has luck with women is considered a 'player' while 'player' also refers to the protagonists of the Hunie games.
