Game Outline

A life together with a curious and selfish demon king who has zero sexual knowledge!

More than 100 sex events, including the second and subsequent events with different dialogues!

Favorability: Both the main and sub heroines are equipped with a “degree of affection” system!

The sex escalates as the likability and affection level increases…!
(Both main and sub heroines have sex)

Daily pants system!
Manamia, the main heroine, is a girl, so of course she changes her pants every day!
And you can ask her to show you her pants every day, so you can enjoy different pants every day!
You can throw lines like “cute”, “erotic”, “childish”, and so on.
If you get to know her well, you can even see through her pants on the spot…?
(If you buy pants, she will wear them automatically.)
(You can also have the main character change into the pants you want him to wear.)
(The demon king only wears cute pants)

You can also go on outings to parks, arcades, and lingerie stores.
Manamia can work at a maid café or a snobbery store.
If you spend a lot of money, you can even go on a date!

And at night, you can do even more!
You can interact with the sub-heroine’s landlady.
Play pranks on the sleeping Demon Lord
Use the pants in the laundry basket without permission
Go out for “spinal cord”!
You can do a lot of things at night!

The main character’s (you) actions change his/her sex status!
A touch system that changes all the lines as your affection level rises!

And keep loving and loving the Demon Lord!
That’s your goal!
