I can't speak for others (obviously), but when I read the manga of Immoral Guild, I just found it meaningless.
They head out into the woods and get molested. By accident.
Then they go home.
The cycle repeats and repeats. Because there is no intelligent belligerent force, the molestation is not a temporary falling-behind in a prolonged struggle (against that antagonist), but rather a personal failure. Like a clumsy person might stumble and fall on her face.
But then it happens again and again and again.
It's frustrating. You read of the misadventures of a band of buffoons who lack the faculties to fix their lives.
There's also a boy with them who keeps getting blueballed when his teammates are getting up to sexy stuff around him whereas he is never getting any.
From every perspective, the story was just endlessly frustrating.
