DID Adventure ~Escape From The Abandoned Factory~

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.”

Help Rena Escape.

Six months ago a virus broke out in Z City.
Kousuke and Saya are step-siblings left behind in this hell,
having survived in a shelter that's no longer habitable.
Options are slim... but before they make the decision to abandon the city,
they respond to a cry for help from a destroyed parking garage.
That choice changes Kousuke and Saya's fates completely...

The strongest adventurer duo, Anna and Relatone, take on a request from a corrupt noble — only to fall into a trap and be saddled with a massive debt.
To free the captured Relatone, Anna desperately searches for a way to make money.
But a busty, beautiful girl in financial trouble is the perfect prey — and there’s no way the lustful men around would let such an opportunity slip.
Anna, sweet-talked and manipulated, ends up giving her body to a worthless man.
Thus, the strongest busty beauty strays from the path… and falls into the hands of a useless man.
