Demo

Initial Release

Developer Notes:

-Prologue-

Due to the Libido Reduction Virus, humanity faced a serious population decline.

The government began developing a vaccine for libido reduction, targeting criminals. However, during clinical trials, a side effect was discovered where if the subject did not continuously release their excessive sexual urges, their DNA would break down, causing severe physical deformations. Despite the failed clinical trials, experiments continued on the test subjects, but one day, the lab was destroyed by an unidentified terrorist group, allowing the imprisoned test subjects to escape.

Yuri Hanasaki looks around in response to the people’s screams. Mutant creatures were attacking civilians.

Remembering her father’s teachings to help the weak, she runs out to intervene…

♥Gameplay♥

Fighting Girl Yuri is a side-scrolling action game.

Use various techniques to defeat enemies.

♥Character Development♥

You can strengthen your character by using status points and skill points to grow even stronger.

♥Items and Enhancements♥

When you defeat enemies, you can obtain item boxes with a certain probability.

There’s a low chance to obtain high-grade items.

Enhance items and challenge higher difficulty stages.

The higher the stage difficulty, the higher the chance of obtaining item boxes.

♥In-game HCG♥

If you get caught by an enemy or remain down for too long, the -In-game HCG- will activate.

In this state, HP gradually decreases, and if it reaches 0, an event animation will play.

Increase your resistance stats to escape quickly.

♥CG Mode♥

If you fail a mission, depending on the condition of your clothes, one of three dynamic CG animations—intact, damaged, or fully stripped—will be triggered.

Collected animations can be rewatched in Gallery Mode. You can customize underwear images in the illustration animations.
