Nagisa is the Angel Probationer / 見習いエンジェルなぎさ

In a world where desire is suppressed by chemicals
and sex itself is illegal, the reproduction rate has dropped to a dangerous low.
An angel is sent to the town where the chemical is produced,
which happens to be where Nagisa lives.

Nagisa is reluctant to join the angel's cause, but she is recruited.
Men need their libidos inspired once more.

Using her mouth, pussy, asshole, the novice angel's limits will be tested
as she liberates the suppressed and endures carnal lust...

Multiple endings - corruption - pregnancy...
Actions have consequences
