About the Game

【Synopsis】

In this world where "human farms" exist.

While regular farms treat their cows well and with respect, there also seems to exist underground illegal farms.

In an effort to take these illegal establishments down, three police officers go undercover to infiltrate them!

【What to look forward to】

This third installment of the "Human Farm" series after "Rehabilitation" and "Practice Section" is also a milking-heavy RPG!

In this new installment, you can take part in a lotof quests around the city outside the farm!

Of course milking is a main part of this series,

but you can also enjoy other fetish plays such as "exhibitionism", "erotic massage", "glory hole", and more!

(!Warning! Parts of the game include limb loss. Sensitive people should be careful.)

There is a mechanism to unlock all erotic scenes, but it will not unlock the different endings.

There are also cheat options who players who do not like action parts.

* The story of each of the "Human Farms" series' games are not in chronological order, so feel free to play them in any order you like.

【Specifities of the game】

【Main characters】

-Iori- (police officer)

Gentle. Has a strong sense of justice.

She can also be clueless and a bit of an airhead?

She is on temporary leave for ignoring her superior's orders. She is secretly investigating undergound human farms.

-Maria- (police officer)

She has a daughter.

She had resigned a long time ago, but she joined to force again to help Iori.

She is pretty easygoing, but she is unbeatable when it comes to hand-to-hand combat.

-Rui- (police officer)

Genius hacker.

She may be out of shape physically, but when it comes to information and machines, she's as strong as they come.

She acts cocky, but she's actually very sweet.

She talks like one of the guys.

-Aina- (cow)

Currently working as a cow.

A long time ago, she did some bad things that landed her in a rehabilitation farm, but she is now a first-class cow.

She can be a bit rude, but she's a very nice person deep down.

-Tsubaki- (police officer)

Iori's senior at the police station.

She's solid as a rock, but there might be a side of her that even she doesn't know?

-Alice- (singer)

A singer that is rising in popularity at the moment.

Apparently, she hides her real identity.

-Karen- (cow)

Currently working as a cow.

Just like Aina, she did bad things that landed her in the rehabilitation facility, but she is now a first-class cow.

She can be a bit dim.

-Boss- (pastry chef)

A true admirer of pretty girls. You could say she opened this café just to see girls in adorable outfits every day.
