Harem life on a dream island!?
It's a harem sex RPG with a lot of volume, with 63 basic CGs and 31 characters to play with!

(Synopsis)
By chance, the main character gets a ticket to an island called Harem Island, where you can have unlimited sex in a harem, so he takes a day off from work to head there by boat.
There were a total of 30 islanders, not including one girl who was acting as a guide, and they were all cute, young women. And they were all naked.
Apparently, the purpose was to make the island prosper with offspring, and for some reason he was lucky enough to be chosen.
Creampies are mandatory during sex, and with 30 naked girls he can proposition at any time, the protagonist's crotch bulges at the possibilities.
Will the protagonist be able to get everyone pregnant in one week?

< Details >
63 CGs! Many ejaculation and orgasm differences!
A total of 31 girls can be conquered!

(Goal)
Communicate with girls all over the island and get them all pregnant in one week.
Don't just call out to her and have sex; instead, plan on having a baby by using various parameters.
If you get everyone pregnant, there will be a reward at the end...?

(System description)
〇Choice of play
You can not only have sex (penetration) with a girl, but also have foreplay.
You can choose to play by talking to the girl.

〇Girls' favorability
This is the most important parameter of this game.
This favorability factor changes girls' attitudes.
If you have a high level of favorability during a conversation, they will talk to you intimately, and they will enjoy having sex with you as well.
On the other hand, if your favorability is low, you won't be able to have a lively conversation, and you'll end up having sex even if you don't like it.
Increase your favorability by talking to girls and giving them gifts.

〇Date event with girls
You can invite girls you like on a date.
The content of the date differs depending on the girl, and the content is varied, with exciting moments, events that develop into sex, and mini-game elements.

〇Other parameters to liven up the game
In addition to favorability, there are other parameters such as physical strength, energy, and pregnancy rate.
The main character always uses up his physical strength, and when he ejaculates, he uses up his energy.
Use various things to recover while playing, and manipulate the pregnancy rate to successfully impregnate your girls.

〇Use of items
You can play the game without items, but to enjoy it even more, use items.
Items include not only recovery items such as physical strength and energy, but also gifts for girls.
Money for purchasing items can be earned through small quests such as gathering and fishing.
(*For busy people, you can also start with a lot of money from the beginning)

〇Girls picture book
This is a convenient feature that allows you to easily see the status of the 31 girls.
You can see each girl's favorability, pregnancy rate, whether she is pregnant, the number of times she has had sex, and whether or not you have talked to her.
You can search for girls you haven't talked to yet, girls you like, girls you haven't had sex with, girls you've dated, girls you've dated, etc.

〇Harem experience system (the reverse is also possible?)
If you have high favorability, girls will approach you.
The more you complete the game, the more naked girls will gather around you. You can truly experience a harem situation.
On the other hand, if you have low favorability, girls will run away from you.
Be hated, have girls run from you, have them protest during sex, and say cold things when you creampie them...
(Although the purpose is to experience a harem, this work is also recommended for those who like that kind of thing.)

〇Strategy elements
In addition to the 30 islanders, you can also try to claim the guide girl (Ellie).
However, unlike other girls, you won't be able to have sex with her unless you meet certain conditions, so your first goal should be to get the 30 islanders pregnant.
In this way, you don't just play by simply talking to girls, there are also strategy elements so you won't get bored.
Get everyone pregnant and aim for the perfect harem ending! (There are several endings as well)
Also, after the harem ending (after the TRUE ending), a bonus element will be added, allowing you to easily watch your favorite scenes whenever you want.
