We learned to play naughty games: Fuun-Aiuchi Academy Flat 2 - Complete Edition

A high school romance visual novel.
Spend your afternoons with the girls you meet across the four stories, and let your choices decide who you grow closest to.
Originally released for mobile by Interactive Studio, now brought to PC as a single buy-to-play edition.
Four separate stories
Four stories, twelve heroines in all.
Every one is open from the start and stands on its own, so you can begin with whichever appeals to you.
After School Sparkles — the sports clubs
Having spent your life trying to avoid unnecessary physical exertion, your perfectly planned daily routine is derailed by a single stray cat.
Now that everyone at school has seen your athletic potential, there's no escaping the three most tenacious club captains as they try to recruit you. It's not all bad though — they just happen to be three of your most beautiful classmates.
Deciding which club to join might not seem that hard, but when feelings are involved the decision is bound to get more difficult.
Student Council
It's a new year, and you're passing the days the only way you know how — hiding away at the back of the class.
When you're asked for help with a simple poster, your perfectly calculated plans for a quiet high school life are dashed: you're appointed campaign manager for the most unlikely student council president in the whole school.
After a disastrous start to the campaign, can you win over the rest of the students, or are you destined to sit on the sidelines forever?
Performing Arts Club
The circus is in town! Or more like, the performing arts club is here and you've been dragged into it. The school's smallest club is on the brink of disbandment, and you've been roped into helping them gather more members.
There's never a dull moment when you're with these passionate performers. Get whipped into shape as you juggle your new club responsibilities with the affections of its members.
Can you really save the circus?
Magical Occult Girlfriend
After running away from home, all you want is to live a normal high school life. But then one of your classmates tells you she started sleeping with scissors to chase away nightmares. That can't be real… right?
Investigating, you find the source of all the weird superstitions is none other than the occult club. It has quite a few eccentric girls in it, but you join anyway, determined to debunk their claims.
Things only get weirder from there. Can you separate fact from fiction, or are you in over your head?
