Naive Girl Illvina

Makoto Hirata is a pessimist who struggles to connect with people. His best relationship is with his childhood playmate, Mizuki. One day, by chance, Makoto witnesses the school "playboy" Hasegawa having sex with a girl classmate. Discovering a kind of thrill in the act of watching, Makoto continues to spy on him.
Before long, Hasegawa has moved in on all the girls Makoto knew and cared about... and finally, with the only person he could call his friend.

Nerisha is a young adult succubus who has never had sex. This is something of a problem to her because succubi can't fully develop their magical powers unless they have some sweaty fun with humans or other humanoids. However, having high ideals of equality, Nerisha is unwilling to get herself a sex slave as most other succubi do.

Serena is a human explorer who got separated from her expedition after something unfortunate happened. She's a mature woman with plenty of sex appeal that she doesn't hesitate to put to good use.

The two women meet as Serena accidentally stumbles upon Nerisha's doorstep. After learning of each other's circumstances, they strike an unusual deal. A deal that involves the two of them having lots of sex...

In a far off era, a far off world.
War has ravaged the land. It's a time of death, and chaos.

Elise is a mercenary that's lived off the war together with her comrades.
But one day, she returned from negotiations from her employer to find her entire squad dead.

Scouring the tragic scene, she sees her powerless, cowering little sister, and a mysterious,
but beautiful lady in white. The two disappear into the darkness, leaving Elise to herself.

Elise begins her journey to find her little sister, and get vengeance on those that felled her allies.

The prideful knightess dons the devil's armor, and as her purity is violated away,
so too does her power grow.
Getting violated, then violating, then cum-squeezing! A devilishly paradoxical HRPG!

Fumika crossed the ocean to move to a greater land, became a heroine to save people, and began her journey...
A girl with pony tails who is dere-dere and a little too lewd.

The protagonist is a trainee teacher who commutes to a certain girls' school.
Safely finishing the daily practice period, and becoming a regular teacher is his goal.
However, his mind begins to tire.
Uneasiness and nightmares come in sudden attacks, causing a strain, a social phobia, begins to grow more and more every day.
Slowly a fear of the girls he meets with after school begins to emerge, yet at the same time, a desire and passion.
Disgust, a kind of taboo, such a feeling is directed to the adult women who are his colleagues.
"Am I really fit to be a teacher?"
Day by day, the pressure builds.
Even when the lessons are over, the lights are off, and the school is closed for another night.
He cannot help but wander.
