Slice of Venture: A New Start

Life has been nothing but Ls for protagonist Koichi Hirose.

Back in college, his first-ever girlfriend dumped him outright, and he ended up dropping out altogether not long after.
Now he’s just trying to hold down a job to make ends meet, but for some reason, every company he joins goes under...

So when his latest hard-won job vanishes overnight (again), he heads to Akihabara for some aimless daytime distraction...

No savings, no career, no girlfriend. Where did it all go wrong?

He sighs into the crowd, then to no one in particular—

“...I sure could use a little love right about now.”

In that moment, only feet away, Mami Mamiya is searching too.
This pink-haired succubus is on the hunt for a human connection.

Not just any connection, but a male with certain innate powers.
Despite the odds, she finds him at once—in our protagonist, Koichi!

And so the story takes a demonic turn.

Tempted by fate and a mysterious invite from Mami, Koichi hitches a ride with her to her remote mountain home.
Little does he know that he might never return...

Or will he...?

Koichi is shocked to find that he’s in no ordinary human village.
He is now in a succubus sanctuary of sorts, hidden from human eyes.

Why Koichi?

After years of self-imposed isolation, a human male is just
what Mami’s village needs to reacquaint with the outside world!
Even touching succubi, however, can be lethal to the average joe...

Not our Koichi, though. This boy’s built different.
With the village’s blessing, let the succubus sessions begin...

Good evening,
can I ask how to start the game? After downloading and extracting the game I tried to start the BGI.exe, but nothing happened. Since I only know games which have a game.exe I thought this BGI would be the same.
 
After trying the BGI, I tried the BHVC.exe, which saif, that there is an error in the sysprg.arc. Does anyone know how to fix this?
I tried to set my pcs locale to japan, but that didn't change anything either.
 
I hope this is the right place for this topic. If not, I'm very sorry.
 

I always get this message. Help
 

The protagonist begins living together with his girlfriend Kanako Tsukishima, whom he started dating as a college student.
Compared to sweet romance, living together requires facing many practical problems.
Players plan a daily routine that balances academics, life, and romance.
As a boyfriend, it is also important to satisfy Kanako’s body and mind.
Too much sex will make her hate you, while no sex is allowed, of course.
The 26 weeks that the protagonist and Kanako spend together will determine the ending of their relationship.
The game has an auto-save system.
For the sake of realism, the player’s previous actions are recorded,
conversation with Kanako and her reactions will differ.
If you do not listen to her voice properly, you may be rejected.

The long war has ended, leaving knights and mercenaries without work.
Living quietly in the tavern left by your grandfather, you one day take in a lone woman.
Your carefree retirement comes to an end, and a busy life of running the tavern alongside Lily begins...
