An exciting cohabitation life is about to begin—
This is a sweet time that belongs only to you and her: a cozy little home, a private world for two.
《Idle Days With Her》is a romance × idle × life simulation game. In daily life, you will grow together with her, deepen your bond, and create a story filled with both sweetness and challenges.

The protagonist lived a modest daily life together with his younger sister, Haruka.
But one day, Haruka suddenly transforms into a succubus, tells him, “It’s a game of tag,” and vanishes from sight.
Thus begins an adventure at a succubus-hunting guild, all to reclaim his sister.
However, the world has now fallen into a state of broken gender ratios, with succubi in abundance. It is a world far too cruel for men.
He gets milked at the guild, milked by female criminals, milked by succubi…
In this harsh world where defeat equals immediate reverse rape, can the protagonist ever find his sister Haruka!?

Yuichi and the anime club successfully fulfill their long-held dream of exhibiting at the doujin event “Comiko.”
The after-party is held at a newly opened luxury party lounge in town.
Yuichi has resolved that tonight is the night he will finally confess his feelings to Maki, the girl he has loved for so long.
Maki is a plain, reserved otaku girl, yet her overly voluptuous chest naturally draws countless stares.
Kaito, a normie (popular guy) who recently joined the anime club, is one of those watching her.
Unbeknownst to anyone, he has been quietly setting his plan into motion.
As the drinks flow, the party’s excitement reaches its peak.
What started as an innocent round of the “King’s Game” soon corners Maki into a dangerous situation with no way out.
Will Yuichi be able to protect Maki and seize a future for the two of them—?

The protagonist was just an ordinary man living a normal life.
But when he awoke, he found himself not in his familiar home—
but inside a secluded house deep in the mountains.
Beside him stood a beautiful girl dressed in a shinobi outfit, who calmly said:
“You have been brought here as a breeding candidate.
For the sake of our village’s survival… we ask that you provide your seed.”

This is the story of a brother who is a substitute teacher at a school and his sister who is a student at the same school.
His sister, Jurina, is a bratty and unruly girl who is always a headache.
One day, when she hears a rumor that the protagonist is getting close to a fellow teacher,
she confronts him and, ignoring his wishes, forces him to ejaculate.
After filming him in an embarrassing position, she says to him…
“From now on, I’ll be your ejaculation manager.”
